Yesterday got new 375.39 long-lived branch update. And today i woke my computer a suspend / standby mode. I got colourful garbled window edges and corrupt title bar.
It is same problem with corrupted window borders etc. witch show versions 378.09 and 375.10.
Only rebooting fix the problem. But when go suspend/standby same border problem show again.
In 375.26 version has not corrupted window borders.
Im using Ubuntu 16.04 LTS. NVIDIA GTX 770
