possible compositing video driver problem locks system

First time user of opensuse. Fresh install of tumbleweed last night using install defaults. K-menu popups, multiple windows, dragging window, or dialogue popups quickly lock system. Occasional spots of pixelation appear on desktop. Have to cold boot to unlock system. Have nvidia 650 ti. Could use advise on debugging or fixing problem that involve use of console or command line since use of windows locks system. The compositing and video driver problem is just a guess. I have minor to moderate linux experience.

Guess I’ll partially answer my own question. Turn compositing off and nothing locks up. Installed the nvidia drivers and with compositing turned on everything works. Same thing happens in 13.2.

Will stick with 13.2 since the nvidia updates are much easier. Too bad though, really liked the look and layout of tumbleweeed.
