Description Geroge T 2018-05-25 19:36:15 UTC
With nvidia proprietary driver no problem, but with nouveau, some gnome apps display black color items. See attachments. It happen on tested kernels "linux-image-4.15.0-22-generic" and "linux-image-4.15.0-23-generic" on ubuntu bionic-proposed.

The black patterns appear when moving the mouse over the items of the GUI.

What GPU is this?

Check your xorg log. Are you using nouveau or modeset? If the latter, please use nouveau.
Comment 6 Geroge T 2018-05-25 19:53:11 UTC
If I open the gnome software on Plasma desktop same issue for those apps. KDE apps apparently are not affected.

You need to install xf86-video-nouveau. If you're unsure of how to do this on your distro, you need to find distro-specific support to help with that.
