Steps to reproduce:

Some of the last few nightlies have had some weird glitches.

Actual results:

UI at top of webpage has red lines that move/change as I move the mouse.

Windows such as Developer Tools, About are functional but don't display anything.

Buttons on webpages show coloured square overlays

Expected results:

No glitches

BTW, I'm using FF over RDP - If I check the remote PC running the FF instance, I just seen a black square.

Hi Campbell, thanks for the bug report,

Could you please go to about:config, and search for gfx.webrender.debug.gpu-cache, and set it to false. That should fix the red lines.

Then search for gfx.webrender.blob.paint-flashing and set it to false. That should fix the square overlays over the items.

Is it possible that you previously set these prefs to true and forgot about them?

Brilliant, thankyou! All good now!

No problem. Glad it's working

Sorry - I just realised this hasn't fixed the empty windows: https://imgur.com/dnrLoTj

My apologies, I missed that part of the description.

So to confirm, regular web pages and the main UI render correctly, but the stuff like the about page and devtools are blank? How about menus?

If you open a second main firefox window, does it render correctly?

Thanks - it seems to be getting worse. Struggling to render any windows now, but menus still work. Screenshots might help, see attached.

Let me know if you want further details.

If you set gfx.webrender.force-disabled to true in about:config, that should hopefully work around the issue while we figure out what the problem is.

I've just noticed the line Error: RenderCompositorSWGL failed mapping default framebuffer, no dt in your error log, which seems like it could be pretty important. Lee, do you know what could be going wrong here?

On my win7 PC, I could reproduce the blank window problem with sw-wr and disabling GPU process. And similar problem happened on Win10 PC.

Depends on: 1715953

I don't know offhand, Jamie. Let's see if Sotaro's patch to add some extra flushing helps in this scenario or not.

On latest nightly, I did not see the empty window problem on Win7.

campbell_kerr, can you check if the empty window problem is addressed with latest nightly?

Flags: needinfo?(campbell_kerr)

Thanks - Looks like we're all good now! When I tried another win7 box I couldn't replicate the issue - I've now gone back to the original win7 box and updated FF and all looks good. Thanks!
