Fedora 32 + nVidia graphic artifacts on resume - users - Fedora mailing-lists

9 Sep 2020


      Hello all,
after resuming from standby, many applications seem to omit repainting
or refreshing areas of the screen.
The system seems stable overall: applications keep running correctly,
but I can't see important areas on the screen.
For example, I might be able to open my email inbox, but then I can't
archive an email as the area where the control buttons are supposed to
be is entirely white (or black, in other applications).
Or, someone pings me on IM - I can see the text but I can't reply as
the reply area isn't there... you get the idea, it's annoying :)
I've seen this happening both when using Gnome and when using i3.
Since I'm running the nvidia proprietary drivers I'm assuming this is
not related with Wayland, more likely some optimisation of the nvidia
driver or how it integrates with X ?
Would anyone have a suggestion as to how to debug this further, or a
possible workaround?
Maybe some nvidia driver option I could pass on the kernel, or in the
X config file?
I'd highly appreciate solving this, as it's my primary development
machine: having to close all applications for frequent reboots has
become very inconvenient.
Unfortunately I can't easily roll back some update: I had this problem
for many weeks, as initially I dismissed it as "just a glitch"; I had
not paid enough attention to it and hadn't noticed that it was related
to resuming from standby.
This is what I'm running today:
 - linux 5.8.6-201.fc32.x86_64
 - nvidia 450.66
Thanks!
