Text colors in editor sometimes randomly change when scrolling #3295

Open bwarren18 opened 3 years ago

bwarren18 commented 3 years ago

Issue Description

When editing code in an editor window, on very rare occasions, the text coloring that is based on the code content type will randomly change as you scroll down the page. To demonstrate the effect I created a bunch of comment lines between my code.

Other notes: The Minimap shows the same coloring. There also appears to be 'ghost' characters in it. The formatting is preserved if copied and pasted into another program, a new message in Outlook for example. Closing and re-opening VSC fixes the issue.

Another person reported the same issue before and it was closed and suggested to be moved here: https://github.com/microsoft/vscode/issues/120800

Thanks @bwarren18 we have seen this issue at times as well-- but it is a bit of a tricky one that will take resources to debug--thanks!

bwarren18 commented 3 years ago

Thanks @SydneyhSmith, let me know if there is anything I can do to collect more debug information for this.

@bwarren18 Does this only happen when semantic highlighting is enabled?

bwarren18 commented 3 years ago

@andschwa Yes. If Semantic Highlighting is set to false it looks fine; the bug reappears if set to true again.

andyleejordan commented 3 years ago

Helpful to know, thank you!

bwarren18 commented 3 years ago

I wish I knew a way to consistently reproduce the issue.
It seems to happen when a file is left open in VS code for a while.
Let me know if there is any thing you would like me to check when it happens again. Thanks.

andyleejordan commented 3 years ago

I've seen it occasionally, we have a whole project planned to address the semantic highlighting issues. It was helpful to be able to categorize this. I'm contemplating disabling semantic highlighting by default until we have it working better.

OMG it's a horrible feature! I hate it so much!

For others who struggle with it, just set config to: 

"editor.semanticHighlighting.enabled": false,
