I cannot reproduce this. Do you see any errors in developer tools? Does this reproduce with any file and with any change or is it specific to this particular file? https://user-
I can't reproduce it anymore either. I just updated to 1.77.0. Maybe it just happened to get fixed in that version? I can still reproduce though.
Hmm no I can still reproduce it in 1.77.0.
Found it! Seems like the issue only occurs after line 99
Hmm and another requirement is that the file has 1000 lines in total or more I think.
I cannot reproduce. I tried with a file which has 1353 lines and I do an edit at line 600. Do you see any errors in Developer Tools (Help Toggle Developer Tools)? https://user-
I don't think the devtools console contains anything of interest: WARN Via '' extension 'ms-' wants API proposal 'contribEditorGutterMenu' but that proposal DOES NOT EXIST.

So far my hypothesis is that you need a long word wrapped line above the one you're trying to reset. But honestly I'm not sure anymore at this point. https://user-
Hooray, this reproduces when using word wrapping! The root cause is that some properties on the mouse event are not converted from view coordinates to model coordinates. This reproduces with the following word wrapped .txt file:
Seems like I can still reproduce (with and w/o word-wrapping): https://user- https://user-
I ran git bisect and I had to skip a few commits due to build problems, but I believe this is caused by The first bad commit could be any of:
So merging the PR will make the arrows work but will also bring back the issue of also setting breakpoints? That is unfortunate but I think I'd rather have the arrows working.
:+1: I think it's better to go back to the state we had in 1.77 and the risk is minimal as it is a simple revert.
