Howdy. I’m on Arch, using KDE.
CPU = Ryzen 7 2700x, with 6c/12t for Windows 10 VM
Host GPU = AMD RX 590
Guest GPU = AMD RX Vega 56
In the host, I have the AMD’s ‘TearFree’ option set in the xorg.conf file, and KDE’s compositor VSync setting is ‘Full Screen Repaints’.
I get tearing and stuttering after a while in the VM, and Looking Glass throws out periodic
texture.c:316 | egl_texture_process | glClientWaitSync failed
errors in the terminal.
I have to shut down and restart Looking Glass, and it’s good for a while before it happens again.
I have AMD’s VSync turned on in the their graphics control program. I have VSync turned on in the game I’m playing (Red Dead Redemption 2). I have tried KDE’s compositor with VSync on and off. I have used both GPUs as guest and host, doesn’t make a difference.
