Danielsan - sorry for the late reply! Been working on some tweaks to the RockPro64 Recalbox build, as well as a new RetroPie build for both 
To address your comments... it's interesting that the alpha build didn't have those artifacts or gamepad issues. A LOT changed from alpha to beta, including updating virtually all of the libraries in buildroot as well as updating the kernel itself to the latest (at the time) commit. Narrowing down the root cause of both is difficult without specific error messages to go off of. There will be more updates to come, including yet another rebase on the buildroot libraries as well as custom patches to greatly increase the run speed of reicast, ppsspp, and mupen. I don't have a date to give you yet, all I can tell you is that good things are coming. As always, thank you so much for your patience, testing, and feedback!
