1014826 - Invalidation problems with basic compositor on Linux

Status: RESOLVED WORKSFORME

(Core :: Graphics: Layers, defect)

Unfortunately, I'm still having invalidation problems with the basic compositor. I had hoped that bug 994546 was the only bug, but it looks like it isn't. However, I now have an STR that seems to reproduce across two machines:

1. Visit http://asyncmanifesto.org/
2. Begin slowly scrolling down by hitting the arrow key.
3. Hitting the down arrow 3 or 4 times leads to graphics corruption.

This happens to me every time I visit the page in Linux with OMTC (no e10s needed). Unfortunately, it doesn't reproduce on Mac or Windows. I tried it on Linux with twm, and it still happens, so it apparently doesn't have to do with compositing window managers. MOZ_X_SYNC seems to have no effect.

I also have problems with devops Borat.

Ooh, the devops Borat problem reproduces on Mac! Just scroll down a bit and the black area at the top of the page will suddenly shift downwards. Then scroll up a bit and things will really get messed up.

This seems to have been fixed in the most recent Nightly.
