External Monitor goes randomly dark on Ryzen™ AI 9 HX 370 with Bazzite

I recently received my 13’’ Ryzen™ AI 9 HX 370 and installed the latest Bazzite on it, since Ubuntu isn’t considered supported yet. Things work generally well, except for one annoying issue: I have an external monitor connected through USBC. When rendering media-intensive content on the external monitor, such as YouTube videos, the external screen goes randomly black and the whole system needs a reboot for an image to be rendered again. The screen is still correctly recognized and a desktop is allocated to it, but nothing is rendered. I’m on the latest distro and kernel version (6.14.4-103.bazzite.fc42.x86_64) but already had the same issue with the previous version. Has anyone encountered similar issues and found a solution?
Relevant dmesg output below for context: [10430.312560] amdgpu 0000:c1:00.0: amdgpu: Dumping IP State[10430.316113] amd - Pastebin.com

Very similar symptons here on F13 AI 9 HX 370 running Ubuntu 24.

Sounds like you might be hitting this:

To confirm it, consider checking your logs (journal / dmesg) to see if you have errors mentioning something like:

may 06 17:00:48 cheshire kernel: amdgpu 0000:c1:00.0: amdgpu: ring vcn_unified_0 timeout, signaled seq=206212>

And:

may 06 17:00:49 cheshire kernel: amdgpu 0000:c1:00.0: amdgpu: GPU reset(1) succeeded!

To do so, run this:

sudo journalctl --no-pager|grep -P  '(GPU reset|vnc_unified_0)'

EDIT: For the moment I’ve disabled hardware acceleration on Firefox and I haven’t seen it happen again.

Please ignore my previous message. I’ve just seen now you already sent your dmesg :person_facepalming:

Yes, it seems to be the same issue.

Thanks for the quick response. I had a look at the other issue and since I think I exclusively triggered it using Firefox, I’ll try disabling hardware acceleration for now and see if that helps.
