Distros tested: Ubuntu 19.04 (fresh install), Kubuntu 18.04
Tested driver versions: 430.40, 418.56
Monitor: Alienware AW2518HF (non validated).
GPU: GTX 1070ti
-Steps to reproduce-
If you launch a fullscreen game with Adaptive Sync disabled, the screen keeps working normally.
This bug persists until you change metamodes with nvidia-settings (you can change to another resolution/refresh rate and then switch it back for the bug to go away) or logout from your X session and log back in again.
Launching the Unigine Heaven benchmark via terminal when triggering this bug shows this (repeated ad infinitum):
GLFrameBuffer::enable(): unsupported OpenGL error: invalid framebuffer operation
I don’t have another FreeSync monitor to test this with so I can’t write out the possibility that this might be related to this specific hardware only… Nvidia’s Adaptive Sync support on this one seems quite buggy to say the least…
