[nvidia] KDE shows bad pixels after hibernate

[Florian Moll]

After hibernation to disk kde shows bad pixels on home screen (look at attached screenshot)
sometimes there are also graphics related bugs in other applications
when I logout and login again or I do a reboot it works like before

maybe it has something to do with the nvidia graphics card?

[Daniel van Vugt (vanvugt)]

This problem is a *feature* of the Nvidia driver. It also affects GNOME (bug 1855757).

[Daniel van Vugt (vanvugt)]

The fix, as Nvidia expects, is for all OpenGL apps and desktop environments to add support for https://www.khronos.org/registry/OpenGL/extensions/NV/NV_robustness_video_memory_purge.txt

Also there's bug 1894627 tracking the same issue in Chrome/Chromium.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.
