[Unresolved] What the hell is happening here?? (lemmy.world)

Running Linux Mint 21.3 EDGE Cinnamon iso. Linux kernel 6.5.0-41. Not sure what happened here or what the cause was, occasionally happens when using Firefox. It'll bug out like this for a few seconds, then when I move my curser over it everything goes back to normal.

I've also experienced an issue where, when opening a tab or doing something in Firefox (usually Google docs), the entire system will randomly do a partial reboot? best way I can explain it is it'll go black, flash (what I assume is) the BIOS terminal screen, then load in my lock screen; all my open softwares will have closed out and I'd have to open it again. Idk if the system is rebooting fully when this happens or not but it sure as hell feels like it.

Are these related? are they Firefox issues or is something fucky with my drivers?

I've verified everything is up to date like 6 times just in case.

Update: Have not personally resolved either issue. unsure if they are unrelated. I can't seem to replicate the issue, unsure if they will be resolved by a random update or not, though the issues do seem to be fairly recent and known about; see comments for what I found on the Internet.

I've had VMs do this if not enough vram were allocated.

Since this is running on metal, I'd say check BIOS settings to see if you can dedicate additional memory to video/GPU. This is a pretty common feature for laptops and desktops with integrated graphics.

Following that, see if there may be a better non-free driver for your graphics. I'd recommend getting lspci output if you don't know what chipset it is. What model is the laptop?

What you're explaining re: partial reboot sounds like your window/display manager crashing.

The specific laptop model is HP Laptop 15-fc0025dx. It's an AMD Radeon graphics card; lspci lists the vga compatible controller as a Mendocino (rev c1), which this link seems to tell me is used in the AMD Radeon 610M. Unsure how to dedicate additional memory to the gpu from the BIOS (still a linux scrub lol), but checking on some dmesg errors reveals there seems to be a recent bug with a link encoder assignment (whatever that means).
