Thank you for taking the time to report this bug and helping to make
Ubuntu better. This particular bug has already been reported and is a
duplicate of bug 1924624, so it is being marked as such. Please
Update: no flickering in this time period.
Downgrading to an older kernel version (5.0.0-05-generic) solved the
problem.
Aparently the kernel version 5.8.0-50-generic has some problem between Intel
Graphics and Xorg.

Title:
Apps interface flickering

Update: so far, the system has not shown any irregularities. I'll wait
for 3 days because this problem does not have a pattern. It seems to
happen when the system is under high load, but I'm not sure.

Touch seeded packages,
I run Ubuntu 20.04.2 LTS GNOME (Xorg)
Processor Intel Core i3-3110M (HD Graphics 4000)
I'll install an older kernel version (5.0) and test it in the next day at 1PM
(my actual version is 5.8.0-50-generic)
I have already formated my linux, so I don't have the dpkg.log
Here is my lspci:
Same flickering effect for me on groovy. I don't know which packages
got updates back then. As for now, I run 5.8.0-50 and don't have older
kernels. The videocard is this:
00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor
Integrated Graphics Controller (rev 06)
Thank you for your bug report, do you remember what packages got updated
at the time the issue started (the /var/log/dpkg.log record could help
figuring it out)? Could you try if starting an older kernel
