AMD graphics broken in both snap Firefox & Chromium versions after recent update (MESA?)

[bamyasi]

Hi,

I was wondering if this is just me or others have been affected as well.

My PC has AMD Radeon 5500 XT graphics card installed and I am using stock Ubuntu AMD kernel drivers (amdgpu) on Kubuntu 22.04 LTS. A couple days ago, after routinely installing a few system updates via apt, which included some MESA libraries, I noticed that the snap-installed versions of both Mozilla Firefox and Chromium browsers on my computer would open with complete garbage inside their windows, like a window full of blinking color speckles, obscuring actual image. Completely unusable. I have downloaded latest standalone Firefox tarball from Mozilla download site, installed it and it is working just fine on this same computer, including hardware acceleration for video, etc. My guess is the snap libraries and system ones got out of sync somehow. However, I have no idea where I send my bug report: snap? Ubuntu upstream? kernel devs?

Thanks,

Bamyasi

I would think the report should go to the snap devs but don't know how you would do that. I would send it to ubuntu launchpad see if it is already there or if you get any response.

Could be something similar to this… ("OBS 28 & 29 Flatpak Were Broken On AMD GPUs"):
