I've encountered this problem too, is there any solution?

[testforstephen]

pls give more details about what the problem is. It's better to share some reproduce steps.

[caymaynard]

I've encountered this while remote debugging. The values that show inline constantly appear and disappear, which makes it very difficult to debug. It has only started recently.

[davidnussio]

I'm experiencing the same problem with inline variable flickering. It occurs in Java but works in JavaScript. As a workaround, I set "debug.inlineValues": "off".

[alfahami]

I'm facing the same issue, particularly when the debugger runs on instruction that has a Scanner object, especially after prompting the user to input data which was not the case before. It does make debugging very difficult.

I'm experiencing the same problem with inline variable flickering. It occurs in Java but works in JavaScript. As a workaround, I set "debug.inlineValues": "off".

Thank you. It indeed worked.

[Tonio101]

Running into the same problem here. Must have happen with a recent update.
Thanks @davidnussio , workaround fixed the issue.
"debug.inlineValues": "off"

[Tonio101]

Steps to reproduce:
Run debugger for a Java program. I've noticed that this only happens if the window/panel is small for the debug inline text. Try splitting into at least 2 editors and run debugger. You'll see it flickering making it extremely difficult to view and debug.

[maratib]

Remove the following from your settings :
"editor.wordWrap": "on"
this will fix the issue

Video is welcome to show what the problem is.

@maratib workaround is better because is simple to enable/disable with shortcut.

@testforstephen

1. start debugging
2. then shrink the window until the text wraps.
3. inlineValues starts to flickering

[khe817]

I did the screen recording that was requested:

vscode-debug-flickering.mp4

@testforstephen Steps to reproduce are as @davidnussio said.

[testforstephen]

@davidnussio and @khe817, thank you for sharing the reproducing steps. My machine has the setting disabled "editor.wordWrap": "off, that's why I don't reproduce it. When I change it to "editor.wordWrap": "on", I can reproduce it now.

[testforstephen]

Opened an issue at VS Code microsoft/vscode#212142

[jaysonsosweet]

Same here

[testforstephen]

this has been fixed in the latest vscode version. At least, I cannot reproduce it in [email protected].
