Vega 8 rendering GDM grey blank login screen after recent change
I have a user in my discord that updated to today's git build and was greeted with a gdm grey screen. I deleted todays mesa git build in our repos and had them repo-sync to the build from two days ago (20220907.ae7532e0) and it's working again for them
unfortunately i dont have the hardware to bisect myself. his laptop has a 5900HS + Radeon RX Vega 8 iGPU
something between ae7532e0 (9/7) and e6cdffa0 (9/9) broke it. ae7532e0 is the working version we have.
we already tried friday (9/9) + saturdays (9/10) end of day commits and confirmed the grey screen happens on those, and our working version is the end of wednesdays (9/7), so the bisect should be literally only thursdays commits. I've asked him if he'd be willing to try to help bisect tomorrow, hoping he's in a nearby timezone
