Compositor issue after changing GPU


After switching from GTX 970 and nonfree drivers, to RX 580 and free (video-linux) drivers, I am now having graphical issues with the compositor etc as seen in the screenshot below:


I have been, and is currently using the following settings in the compositor:

Using XRender -> Smooth, I have no issues.
I think I want to use openGL, though.

I am in need of assistance..


That noise/grain on the Panel is due to Blur settings. This should help, and probably a log out and back is required after modification.
Try with defaults. Disable and re-enable Blur.



Thank you :slight_smile:

No restart or logout required. Just ajusted the noise strength.
