Visual artifacts when opening windows with mutter 3.36.4

Open shibotto opened this issue 5 years ago • 2 comments

3.36.3 (good) 3-36-3

3.36.4 (bad, notice the blue rectangles) 3-36-4

I bisected the mutter commit that introduced this down to https://gitlab.gnome.org/GNOME/mutter/-/commit/44a3358125317dbe2151cf0ac70ec2c382236881.

I can only reproduce this using PaperWM, vanilla GNOME doesn't seem to be affected.

Right, I suspected there might be some breakage when looking at the release notes.

Thanks for taking the time bisecting the problem. Will take a look.

With mutter 3.38.1 I have a lot of those too. More generally the whole user experience has been degraded with GNOME 3.38 (glitches, latencies, etc.), but nothing I can reproduce at will.

Still a problem (even worse maybe) with GNOME 43 + Xorg and develop branch :(

Thanks @shibotto, your comment re still happening on Gnome 43 caught my attention (I'm also on Gnome 43).

I didn't really notice it (but then again I prefer speeding up animation-time to 0.15). Changing animation-time to 0.99 you can see the selected actor being drawn with the rectangles you refer to for some of the windows.

Will have a look and see about cleaning up / improving the animation/tween used.

Hey @shibotto, sorry it took a while (was working on a few different things).

Anyways, checkout #501 - it should look much better (also I put up some before/after vids in that PR).
