Window managers can work around it by not using Xpresent, but there's

It is, but nobody's making upstream releases, which is probably why users are
still hitting this issue, even though the fix landed upstream 9
Some follow-up with users from the Ubuntu MATE Community forums show

Workaround is to disable the compositor but that breaks applications like Zoom.

I have similar problem with xubuntu & ubuntu studio (fresh install or upgrade) ,
it happen only with some resolutions & without screen rotation.
i "solved" it increasing framebuffer in at least 1 pixel,
eg: xrandr --fb 1441x900 --output DisplayPort-0 --mode 1440x900
--panning 1440x0
try?

You can simply switch back to glx:
xfconf-query -c xfwm4 -p /general/vblank_mode -t string -s "glx"
--create
until the issue is fixed in the driver. Then you can set it back to "auto".
No need to roll back.

I've worked with upstream AMD and we've fixed the problem in in xf86
-video-amdgpu. As soon as that is available in the upstream repository
I'll prepare a cherry-pick update to 20.04.
I suspect we also need to consider an SRU patch to 18.04 ?
