Highlight similar instances of a selected word fails when scrolling - Highlight similar instances of a selected word fails when scrolling I have Quartus Prime Pro 25.3 installed. I also have the text editor option "Highlight similar instances of a selected word" checked. When I double click on a single word, the similar instances highlight (this is expected) but then when I go to scroll with my mouse, all the highlighting of the similar instances then disappears. It used to work properly in all previous versions where I could scroll to see all the highlighted similar instances, but now it doesn't work. Replies: Re: Highlight similar instances of a selected word fails when scrolling I will wait for 26.1.1 Replies: Re: Highlight similar instances of a selected word fails when scrolling If you cannot wait, can provide us a reason? It will be very useful. Replies: Re: Highlight similar instances of a selected word fails when scrolling For this issue, our engineering have plan to fix it in 26.1.1. Do you think you can wait until that release? Replies: Re: Highlight similar instances of a selected word fails when scrolling Just saw your reply in another thread, we shall wait for your video Replies: Re: Highlight similar instances of a selected word fails when scrolling Not sure if you have update for the above? Replies: Re: Highlight similar instances of a selected word fails when scrolling Currently, based on your video, i manage to duplicate the issue with below: When using the Quartus Prime Pro Edition text editor (VHDL/Verilog), the editor selection logic behaves incorrectly after performing a Find (Ctrl+F) operation with the search term left in the Find box when the Find dialog is closed. This results in: Unexpected re-highlighting of the previous search term when scrolling. Selection “jumping” to the top of the file during click‑hold‑scroll actions. Risk of unintentionally selecting large portions of the file and accidentally deleting user code. Possible loss of work if the user doesn't immediately notice the unintended selection. Steps to Reproduce 1. Open Quartus Prime Pro Edition 25.3 (with patch). Create a new VHDL (or Verilog) file. Add repeated occurrences of a token (e.g., event_plan). Highlight one occurrence and press Ctrl+F → Find dialog appears and all matches are highlighted. Close the Find dialog without clearing the search term . Now attempt either: Case A — Scroll after single-click: Click anywhere else in the file to place the caret. Scroll with mouse wheel → selection unexpectedly reverts to the last Find-matched word. Case B — Click-hold-scroll selection: Start a selection (e.g., click-hold at line 50). Drag or wheel-scroll downward. The selection unexpectedly jumps to the top of the file, selecting everything above. Pressing Delete removes large unintended sections of code. If anything is not covered above, can help create a new case and attach a new video? If it is already covered, you do not need to create a new thread. Thank you Replies: Re: Highlight similar instances of a selected word fails when scrolling Are you talking about creating a new thread for each of the "Another bug" comments or another thread for the video I posted in relation to the click scroll and hold that highlights everything up to the top when you have left something in the Find box or all three? Replies: Re: Highlight similar instances of a selected word fails when scrolling can you file another case for this? As we want to address the bug in case by case basis. Replies: Re: Highlight similar instances of a selected word fails when scrolling Another bug that is irritating.... when I press Ctrl + F to find something, older versions started from the cursor. Now it ALWAYS starts from the beginning of the file. So if you are looking for an instance further down after numerous instances, you have to keep pressing Find Next. I used to be able to scroll past a section with numerous instances and then click the cursor on that location and resume the Find Next from there. Now that doesn't work.As soon as I resume, it goes back to the beginning of the file. Another bug not as irritating, if I have moved my quartus program window to a monitor that is vertical (narrow), and perform a Ctrl + F to find something, the attached "find" window appears. Since the window is more narrow, a horizontal scroll bar appears. (I would expect that) Then if I press the replace option within the find box, the whole find box disappears and Maybe these should be another thread, but there are so many bugs with the Find functionality. Who was in charge of that portion of the update!?! That was rhetorical, I don't really care who it was; but maybe they should either take more pride in their work or look for another line of work.

Replies: Re: Highlight similar instances of a selected word fails when scrolling I try the below steps and cannot find the problem, did i do anything wrong? Can you send us the video on what you did? Step-by-Step Instructions for Highlighting Issue in Quartus Prime Pro 25.3 1. Open Your File in Quartus Launch Quartus Prime Pro 25.3. Open the text file you want to edit in the built-in text editor. 2. Confirm Editor Settings Go to the text editor preferences. 3. Test Highlighting Double-click a word in your text file. All similar instances should initially highlight? 4. Scroll to Observe the Bug Scroll using your mouse wheel. Notice that all highlighting disappears as you scroll, i dont see the 3 highligh. Keyboard Navigation: After double-clicking, use the arrow keys or PgUp/PgDn to move through the text. This sometimes preserves the highlighting. (stuck at 3) Find Box: Press Ctrl+F and enter the word you want to highlight. This will highlight all instances and usually persists when scrolling. (stuck at 3) Thanks, Best regards, Kenny Tan Replies: Re: Highlight similar instances of a selected word fails when scrolling kindly expect some delay, I will need some time to attempt duplicate the issue in window 11. Replies: Re: Highlight similar instances of a selected word fails when scrolling Windows 11 Enterprise Replies: Re: Highlight similar instances of a selected word fails when scrolling May I know what OS that you were using? I do not see this problem in the linux OS Replies: Re: Highlight similar instances of a selected word fails when scrolling I would also add (just noticed this today) that if you leave a word in the find box and close it, there is another interesting and problematic bug. If you go to click-hold and scroll so as to highlight a larger amount of text (maybe that you plan on deleting or copying), then shortly after a couple scrolls, all the text above the cursor highlights. Often times without you even noticing depending on how fast you scroll. So be aware that if you press delete, it then deletes everything in the file from above where you started highlighting too! Replies: Re: Highlight similar instances of a selected word fails when scrolling I would note that after using the 'Find' window and you close it, the issue still happens unless you delete the search term before closing it. Replies: Re: Highlight similar instances of a selected word fails when scrolling I was able to successfully reproduce the issue. It occurs whenever the 'Find' window is opened/used. As you mentioned, clearing the text or replacing it with your desired search term in the 'Find What' box resolves the issue. Thanks for the feedback — I’ll ask the tool specialist to look into this. Regards, Richard Tan Replies: Re: Highlight similar instances of a selected word fails when scrolling I feel like I've seen this errant behavior in previous versions of the software, but I could be wrong. Replies: Re: Highlight similar instances of a selected word fails when scrolling I think I figured out the bug and how the problem is created and what I need to do to prevent it. It still exists and should be fixed in the software though. For this example, I will pretend that the words that I am double clicking on and using the Find feature for are "TEST1", "TEST2", etc. When I double left click on "TEST1", all the matching words in the file are highlighted, this is good and what should happen. Then I scroll and I can see all the highlighted "TEST1" words. If I then left click off of "TEST1", the words become not highlighted. This is expected as well. Now, if I double left click on "TEST1" and then press ctrl+F (for a Find), the 'Find' box opens and "TEST1" is listed in the 'Find What' box and I can click the 'Find Next' box to go to each of the locations within the file that "TEST1" is found. This is expected as well. Now at this point, I simply 'x' out or close the Find Box since I was done with searching for "TEST1". Now the "TEST1" word becomes not highlighted. Here is the bug, If I then double left click on "TEST2", those words become highlighted, but when I go to scroll with the mouse, the highlighting of "TEST2" stops being highlighted and "TEST1" becomes highlighted instead. If I double left click again on the "TEST1" word and open the back up the 'Find' box and then delete the word "TEST1" from the 'Find What' box, and THEN close the 'Find' box, the functionality for double left clicking on a word and scrolling is restored. Long story short, if you leave a word in the 'Find What' box when you 'x' out or close the 'Find' box, the software remembers that word and it messes up all subsequent left double click and highlighting of words until the 'Find' box is reopened, the word is deleted, and the 'Find' box closed.
