Daniel,

I note that the mutter reported was using mutter 3.36.6 - this is
currently in focal proposed as well.

I'll do a quick test later - do you think this is a potential blocker
issue for the mutter migration to release?

Ok. On my low end celeron based intel graphics laptop the existing 20.04.1
version of mutter on the iso has this blinking problem.

So the uplift to v3.36.6 version of mutter in proposed does not regress
further than it already is.

Well, the system is still usable and upstream hasn't even noticed the bug yet. So no I don't think this is a blocker.

For 20.04 and 20.10 using the TearFree option has provided a workaround solution for me.

Separately Sam (the issue reporter) has confirmed the same solution for his intel graphics

Great, but keep in mind that's just a workaround. Using the 'intel' driver is usually not recommended because it's getting old and buggy in other ways. It is however your only option if you need 'TearFree' enabled. See also https://bugs.launchpad.net/ubuntu/+bugs?field.tag=tearing

I should also note that Wayland sessions don't have this bug, and don't have tearing either.

Upstream has closed the bug because it stopped happening with:

mutter 3.38.2 + Xorg 1.20.10

We are about to get the first one in Ubuntu so we'll find out if it's enough.

affects:

gnome-shell (Ubuntu) → xorg-server (Ubuntu)

Still happening in focal, groovy and hirsute. :(

Although none of them have Xorg 1.20.10 yet, so fingers crossed.

It's not clear to me which change in 1.20.10 that upstream think solved this. The release notes are here: https://lists.x.org/archives/xorg-announce/2020-December/003067.html

Maybe this fix? https://gitlab.freedesktop.org/xorg/xserver/-/commit/c3e4c1a0fd5d4d6015e9e6317b758018317e56d1

After updating Ubuntu Budgie 20.10 today (5.8.0-44-generic #50-Ubuntu) I notice this doesn't happen for me anymore. It is possible that it just hasn't happened yet, but prior to today, I could reliably reproduce this every time by resizing a window for a few seconds until flickering started. I can't make this happen anymore, so fingers crossed...

Nevermind. I do still experience this in Chrome on 20.04 at least.

I haven't seen this in 9 months or so, so incomplete again.
