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.

    When everything closes, are you sure that’s the lock screen and not the login screen? It sounds like cinnamon is crashing, which means you’re automatically switched back to the display manager (login screen). This can sometimes show the boot logo while it’s switching, happens on my laptop as well, noy sure why that is. If it is crashing, you might find the cause in the logs, run journalctl -e and dmesg to check for errors

      yeah you’re correct, it is the login screen and not the lock screen. it just happened again while I was leaving my laptop running and playing music. I’ll run those commands in a little bit, otherwise occupied atm

      I checked the logs. I really don’t know how to use journalctl -e at all, so I’m just going to mention what I found on dmesg. It reported a number of errors, though they were mostly the same. This one came up pretty often:

      [drm:link_enc_cfg_validate [amdgpu]] *ERROR* link_enc_cfg_validate: Invalid link encoder assignments - 0x1c

      and these two come up a number of times, always together:

      [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring sdma0 timeout, signaled seq=13767, emitted seq=13769 [drm:amdgpu_job_timedout [amdgpu]] *ERROR* Process information: process pid 0 thread pid 0

      I got an error for the bluetooth a couple times too: Bluetooth: hci0: Failed to read codec capabilities (-22), and this other one only came up once iirc: hub 6-0:1.0: config failed, hub doesn't have any ports! (err -19)

      I don’t think the hub or the bluetooth errors have anything to do with the crashes, so I looked up the first error, the invalid encoder assignment one, and found this thread from a few days ago, though it doesn’t seem to have any solid answers other than rolling back to an older linux. Most recent post seems to be from 2 hours ago lol, I guess this is a really new issue?
