Public bug reported:
The issue is screen glitches
issue is intermittent and temporary
I think it started after a recent update
But it gives the impression of an unstable system
things flickering like a highlighted file in nautilus or in filezilla
shadows under dialog boxes flickering
the icons in the activities bar flickering like its displayed twice but
scrolled vertically
there are flickers of the other apps behind each, and some appear highlighted
as they do when you put your mouse over them
by scrolling them manually and running mouse over them seemed to get it to stop
it
didn't stop immediately but it did
sometimes unresponsive apps like zoom
sometimes zoom showing empty dialog
a symptom that has existed for a while in nautilus when deep in a directory
structure the top bar
containing directory names flickers like its scrolling horizontally.
I click on a higher folder to get it to stop
all the above happen regardless of where the mouse is
in gedit with multiple tabs open one tab (the tab) appeared blank no
file name, no flickering
Ubuntu 20.04.2 LTS
Laptop model Asus N550JV old
16GB RAM
mouse is new but basic wired J.BURROWS
had to replace small one becuase button got stuck and it kept double clicking
when i only single clicked
Additional relevant
I recently updated twice
normally I wait a while perhaps a month before I update
I think it started after a recent update
Additional
I do have many app running at the same time
many opera windows 5+ with many tabs each 30+
which drains my ram 16GB
Has both NVIDIA and built in INTEL graphics
at the time NVIDIA is turned off using INTEL
could be related to RAM or maybe mouse
Additional minor
after latest update my desktop wallpaper which was just ubuntu 20.04 default
now appears black
in settings I can choose others and they display, but choose the one it was it
stays black
actually I would like an option for black. save power graphics CPU
I really would like a ubuntu without screen glitches
Thank you for your time
