output from emerge --info

recently I noticed missrendering of heavy webgl websites, best example is windy.com 

I had unstable =media-libs/mesa-23.1.3 keyworded, downgrading to =media-libs/mesa-23.0.3-r1 fixes the issue 

emerge --info is attached

Could this be the same issue as https://bugs.gentoo.org/907431?
Comment 4 tt_1 2023-07-14 13:49:49 UTC 
might be broken firmware, I have amdgpu
Comment 5 Sam James archtester Gentoo Infrastructure gentoo-dev Security 2023-07-14 13:54:51 UTC 
Or maybe bug 910262.
Comment 6 tt_1 2023-07-14 16:57:53 UTC 
linux-firmware is not at fault, there was no change in checksums for my Polaris10 setup

I removed ~/.config/opera/GPUCache dir and restarted opera, it is now very stable to me with current stable =media-libs/mesa-23.0.3-r1 

please allow me a bit of further testing with the unstable mesa, before closing the bug
Comment 7 tt_1 2023-07-16 11:46:22 UTC 
This seems to be ok with =mesa-23.1.3 as well, do you mabye want to add some nice elog note to promote the purging of the gpu cache? 

I wonder if firefox will hit the same bug, with the recent skia upgrade.
Comment 8 tt_1 2023-07-23 13:58:32 UTC 
alright, case closed. solution is to force the gpu cache to be regenerated by deleting it. using mv also works, if you're skittish and need a backup.
