From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

On your gf's system, is hardware acceleration configured correctly?
I'll need to dig deeper, but she is guarding her pc like a mother lion guarding a cub. I ran the commands - vainfo, vdpauinfo, and vulkaninfo | grep VK_KHR_video_ only vulkaninfo kicked back what it should have. I tried the same commands on my system with the same results and we are using the proprietary Nvidia driver NVIDIA driver (open kernel) metapackage 580 (proprietary, tested) only on her system it doesn't say "device using recomended driver" so I need to find the recommended one for her but she is in the middle of minecraft and youtube and doesn't want to reboot now, hopefully sat I can when she is at work
You said this happens during Elder Scrolls Online, right? Maybe have her close the game’s launcher while the game is running. In my case, I noticed jittery performance in everything, including moving the cursor, until I closed the launcher. May or may not be the issue, but it does sound similar to what happens to me when I leave that game’s launcher open.
She does close it as even on windows she found it made the system laggy, and it appears hardware acceleration is on in firefox but I think the snap is installed (thought I installed the flatpak same install on my system), every setting is the same as mine.
Damn, I really wish I could offer more help beyond ensuring drivers are set up correctly for NVIDIA. I mean, you could also check the power profile too, using something like cpupower-gui to see if it’s in power saving mode. I suppose you could also close other applications to see if one of them is interfering, since you said Firefox may have something to do with it. I suppose it’s possible Snap has something to do with it too.
