Short description of error
Menu flickering under wayland.

Exact steps for others to reproduce the error
In Blender set "Window Draw Method" to "Triple Buffer"
Login to KDE/Gnome wayland session
Go to File menu(its the longest, easier to trigger) and simply move mouse pointer up and down a few times.

P.S. When are you planning to add wayland support? Thanks.

If Blender works properly with Window Draw Method set to Full, then this is not a bug. That is simply the setting that plays nicely with your particular graphics card + driver.

Corrections welcome. Otherwise, I'll close this later.

Bastien Montagne (mont29) claimed this task.

We do not have to "support" Wayland afaik, this is low level compositor API that is hidden to most applications behind higher level APIs…

Anyway, this sounds more like driver issue (are you using official AMD ones?) than anything else.

I'm having the same issue with flickering under Wayland, regardless of the draw method used, although full does help a little bit, I also get black flickering of the 3d viewport when circle selecting vertices on wireframe view.
I've verified that this only happens under Wayland, the exact same setup, same drivers and kernel under X11 works just fine.
I'm using a RX 560 with the amdgpu drivers, kernel 4.13, although I tried 4.9 and 4.12 as well.

Other software using SDL doesn't have this issue that I've seen.
