Description

For about a month now retroarchs glcore renderer is broken on the steamdeck.

How to replace. Go to desktop mode, update all the dependencies in the discover store. Use the latest retroarch version. Switch to the glcore video renderer, and retroarch will blackscreen (on restart for sure. :) )

I'm using shaders and filters together often, and glcore was the best renderer to use for that purpose.

I'd be over the moon if you could make it work again on the steamdeck (steamos).

Thank you,

One more thing, the renderer seemed to break, because of a steamdeck driver/dependency update, not because of a retroarch update. Filed a bugreport with steamos as well, but they havent responded. Linux dependency mismatch of some sort seems to be the most likely culprit here.

Research direction

Reproduce on a Steam Deck running SteamOS: update dependencies in Discover, use the latest RetroArch, select the glcore video renderer, and restart. Investigate the reported driver or dependency mismatch; done means glcore no longer produces a black screen, including when shaders and filters are used together.
