I have problem with ma Plasma desktop running on wayland. It's work really good, but sometime desktop flickering. It's look like some problem with refreshing or something like that, everything blinking when I switching between applications. I add movie with my problem: https://www.youtube.com/watch?v=uGMamwht4jM My machine: Dell precision M4400 GPU driver nouveau
I have some similar flickering/artifacts in: Distribution: KDE neon Developer Edition Unstable Branches live iso 20170813 KDE Plasma Version: 5.10.90 KDE Frameworks Version: 5.37.0 Qt Version: 5.9.1 Kernel Version: 4.10.0-32-generic OS Type: 64-bit Video Card: Intel 4500MHD That happens not exactly when switching between windows - but it seems to happen upon various other activities too: moving, minimizing, maximizing windows, etc. Reproducibility: Rarely
I noticed flickering happens sometimes upon activity in Kate - saving/editing files.
Also i noticed flickering from time to time upon activity in Konsole and there is also rare flickering when there is no input from user side.
Probably flickering can be generated random by any software. When it's start, then is impossible to fix in. Only restarting wayland can stop it.
I have ASUS N56VZ laptop with NVIDIA card, using NOUVEAU driver. Previously secondary monitor was always connected to laptop and all works OK. But when I disconnected that secondary monitor then this flickering and "hangs" (delayed screen update while showing several frames old picture or picture from midway of animation) starts to happen.
Can confirm on Plasma 5.14.3 and nouveau KF: 5.52 Qt: 5.11.2 Graphics: Card: NVIDIA GT218M [NVS 3100M] Display Server: wayland (X.Org 1.19.6 ) drivers: nouveau (unloaded: modesetting,fbdev,vesa) Resolution: 1280x800@59.99hz OpenGL: renderer: NVA8 version: 3.3 Mesa 18.0.5 https://youtu.be/ufb7KWG28Y0
It's working really nicely for me in Plasma 5.21, no flickering. Is anyone able to reproduce the issue with this version or a newer one?
