1124727 - Browser Toolbox: Debugger source pane flickers

Status: RESOLVED FIXED

(DevTools :: Debugger, defect)

Description

[J. Ryan Stinnett [:jryans] (Use needinfo, replies may be slow)]

Attachment: Flickering Example

STR:

1. Open Browser Toolbox
2. Switch to debugger
3. Choose a source file
4. Click in the editor frame

It should now flicker to dim text ~3 times before stabilizing.

See attachment.

5. Scroll the source pane

Flickering repeats on each scroll action.

I've seen this issue for a long time, so I don't think it's a recent change.

That is weird, looks like the same font rendering issue when a DOM element goes from being hardware accelerated on the GPU to not. I can't reproduce it but I haven't tried the dark theme. Any chance you could try the light theme?

It happens on both themes for me.

this relates to the old debugger.
