Title:
Resizing any window will randomly result in graphics corruption for a
fraction of a second
Status in gnome-shell package in Ubuntu:
Incomplete
Status in mesa package in Ubuntu:
Incomplete
Status in mutter package in Ubuntu:
Incomplete
Bug description:
When resizing any window in any direction the window can appear glitchy as
presented in the screenshot.
This glitchy appearance is restored immediately.
The issue seems to be seen less often when the CPU is utilized more heavily,
as when I recorded the screen with OBS to grab the screenshot.
The screenshots shows gnome-system-monitor, but I could trigger it with
Firefox, gnome-terminal and others.
No such issues were experienced with previously installed Ubuntu Mate
or Windows 10.
