My system has the following Nvidia:
VGA compatible controller: NVIDIA Corporation GA102 [GeForce RTX 3080] (rev a1)
All fedora packages are updated.
I also already disabled all gnome shell extension but same problem.
In the following picture the settings->about details.
It works fine here (both the online accounts dialog and showing GNOME version). Try creating a new user account and use online accounts there. Do they display correctly?
You can check whether you’re not missing any Workstation packages by running:
sudo dnf group install workstation-product-environment
(that could fix the GNOME version display, but unlikely the rendering).
You’re likely to have lots of issues with Nvidia on Linux. If it’s enough to drag/resize the window to display the content, I’d say that’s a good enough workaround.
Some seem to have issues, but in many years of using nvidia I have no issues.
Only the newest cards (3000 series and newer) have even had issues with installation for me, and that is because the nouveau drivers do not support them properly. Even with those cards the installation can be easily done by using the basic graphics mode then installing the nvidia drivers from rpmfusion.
