Display artifacts with Nvidia GPU

john01dav · 2020-12-06 07:05:48

Recently, I noticed that random bits of my computer's UI don't update when they should. For example, I might switch tabs in Firefox and the tab bar changes instantly, but the web content / web view waits a few seconds before changing, and sometimes only part of it updates at a time. Sometimes I even need to resize the window to get it to fully render. Similar things are happening in other applications. I have a GTX 1070 with driver version 455.45.01 (proprietary, unless some update undid this) on Xorg (again, unless some update undid this). What could cause this? Is my GPU on its way out? (My last 90s-era computer had different graphical glitches and it was a warning sign that the GPU was about to go bad, but, of course, a lot has changed with GPUs since then.) I would just try with my integrated graphics, but doing so changes the entire driver stack as well, which could easily make a simple misconfiguration look like a failing GPU (or visa-versa).

More likely insufficient damage events.
Which desktop environment/compositor do you use?
In doubt, post the output of

loginctl session-status

I use Gnome with all the defaults, except lightdm and Xorg. The output of hte command:

$ loginctl session-status

I would also like to note that this seems to happen intermittently, and a restart seems to temporarily fix it, until a later restart when it comes back. I'm also having an issue where my password gets rejected usually in sudo, although now in lightdm, until I restart and then it is accepted again.

Can you reproduce this in, say, an openbox session (notably uncomposited)?
