ubuntu - Pixelated window borders and buttons -


i have no idea how happening, upon returning sleep computer messes floating windows , right-click menus. weird pixelations happens around window border , close/minimize/maximize-buttons, not when window maximized.

problem goes away after reboot, reappears after system return sleep.

any suggestions how troubleshoot this, appreciated!

screenshot of error

i tried changing theme default, doesn't help, don't think it's related theme. looks more hardware-issue :-/

i can't link duplicate questions / answers, here, assuming have nvidia graphics card, permanent fix downgrade nvidia driver version 375 361. full instructions available in linked post.

otherwise, temporary fix restart unity (just type unity in shell).
