Retroarch - White Rectangles UNREADABLE TEXT Workaround
5I recently went through three days of hell trying to find a solution to this problem, and it only seems to affect Retroarch. I show you the solution in this video and also play two short demos of Ruff N' Tumble on Commodore Amiga.
On Linux, updating your system, installing wine, or installing anything else extensive (with a lot of dependencies) WILL cause this bug with OpenGL font rendering. Fear not, the solution is actually not a fresh install, but editing a cfg text file.
---------IMPORTANT UPDATE---------
After you change your video driver, you will notice your shaders have disappeared, and you are unable to use shaders anymore. All you have to do is go to Online Updater - Update Shaders. Retroarch will download the slang shaders package, and then you can select them in game.
