Hello,
starting with recent kernels of 4.18.x series, I have a problem concerning the mouse pointer, as it can either disappear or flash and, when hovering windows, like for instance dolphin, it literally moves "squares" around the pointer.
This happens when composting with openGL 3.1 and 2.0 but NOT with Xrender, which, unfortunately, disables great part of the desktop effects I like to see.
This is my graphic card, always performed great with noveau:
Graphics: Device-1: NVIDIA GF106GL [Quadro 2000] driver: nouveau v: kernel
Display: x11 server: X.Org 1.20.1 driver: modesetting unloaded: fbdev,vesa
resolution: 1920x1080~60Hz, 1920x1080~60Hz
OpenGL: renderer: NVC3 v: 4.3 Mesa 18.1.9
Is this due to noveau or to KDE implementation of openGL?How to solve it?THX
