NVIDIA and Clutter window repainting bug

Latest response

There appears to be a problem with the latest NVIDIA drivers and Clutter which is causing portions of a window to be repainted instead of the entire window. This results in a window showing old and new content at the same time.

The specific issue, according to this NVIDIA forum thread (https://devtalk.nvidia.com/default/topic/690704/linux/-334-16-parts-of-the-ui-randomly-flicker-when-moving-the-mouse/post/4128101/#4128101), indicates the problem has to do with how the buffer_age extension is being handled in clutter.

An official bug fix has been pushed to upstream and I'm curious if it can be pushed into RHEL 7.1?

Update:

I found a workaround to the issue described above. It seems the throttling of the video card (for power savings) causes a timing issue with clutter creating the anomaly. As a solution, the following device option can be added to an Nvidia X configuration file:

Section "Device"
Identifier "Device0"
Driver "nvidia"
VendorName "NVIDIA Corporation"
BoardName "GeForce GTX 770"
Option "RegistryDwords" "PerfLevelSrc=0x3322; PowerMizerDefaultAC=0x1"
EndSection
