An issue that I believe is related is the Quadro T2000 in my Thinkpad P1. Randomly(usually when something graphically intensive starts to happen like redrawing windows) the screen will briefly flicker.
I have disabled the open source drivers, am on a 5.8 kernel, and installed the nvidia 350xx bumblebee driver for use with my igpu.
I know it would most likely be solved if I used x11 over wayland, but the wayland style gesture support is crucial for my workflow, and libinput gestures don’t work as well.
If anyone has any ideas as to what is causing this, I would love to know. It isn’t breaking anything, its just annoying to see a quick flicker, and since the flicker is pure white it does hurt the eyes a bit lol. More importantly, its the last thing on my fix list until all the laptops features(Facial recognition, fingerprint, dolby atmos) are working 100% perfectly, and that’s driving me crazy!
