osu! version: 20170731.1beta

Hey!

Try installing osu! with the old installer.

Also make sure your graphic drivers are up-to-date.

Well judging from the message i think its graphics related but i dont know anything about it so... cant help..

Using the old installer seems wo work ty vm

This is 100% caused by not having your Graphics Drivers installed (or them being broken or outdated) or your GPU doesn't support the correct OpenGL version.

This also can happen if you are using 16bit colors instead of 32bit

Using the old installer will put you on Fallback, a really old outdated version of osu! that shouldn't be used unless nothing else works (and is missing a lot of features)

This would make sense since in settings i get forced to use stable mode

So in the end i guess the colour was the problem, for some reason i had 16 bit instead of 32 bit fixed it now it works just fine ty
