@mferrari do you know if uninstalling SDL2-DEV via apt fixes the problem? Or once it’s installed is retroarch speed affected even if SDL2-DEV is removed?

I recently installed it to build some other emulators and I’m not sure if I’m witnessing a slowdown or not. Kinda feels like I might be, but I didn’t do very thorough testing or take notes prior to installing so I’m not sure.

For the snaod printer issue, I found a post we must have all missed from a month ago that suggests a fix. I haven’t tried it because so far I’ve avoided installing snapd. Hopefully if this fix works, it’s something the ClockworkPi folks can update for everyone eventually, but until then it sounds like the manual fix may work.
