Windows(Dolphin, FF, ect...)opens in the smallest size possi

EVERY single window opens in the smallest size possible!!! EVERY single app does that! It’s REALLY annoying! I never had that problem before. I have recently reinstalled an nVidia driver(180.25, newer bugged). All my specs are in my siggy. BTW, I “reinstalled” openSuSE but moved my /home from a backup(gotta create a seperate partition for my home) so this MIGHT be the problem.
