Hello,
I have just made a fresh installation of the latest EndeavourOs Snapshot (Atlantis neo). Unfortunately my desktop is flickering - not constant but irregular without a noticable trigger and even while idle. It’s like having a kind of silent thunderstorm in my monitor with occasional lightnings 
However it is a quite disturbing and distracting and so I would like to ask for help. Thank you very much in advance for any suggestion and - hopefully - solution!
Things I observed:
- The flickering happens even in the live session of a fresh USB Image. I tested different USB-sticks and have checked the .iso - file before flashing it.
- The flickering seems not to be dependent on my desktop-environment. At least it happens under KDE and Xfce alike.
- Same for Kernels (at least the standard and the zen kernel. My GPU is too new for 5.10 LTS)
- I have used EndeavourOS before (same hardware setup) with the snapshot from Aug 27th. I have not experienced any kind of flickering I can remember of. And I am quite sure I would.
- For comparsion I have tested some other linux distributions. I have no flickering with OpenSuse Tumbleweed (KDE, 5.15 standard Kernel) and MX Linux 21 (Xfce, 5.14 standard Kernel), however Mageia 8 (KDE, XFce, 5.15 standard Kernel) has the same issue like EndeavourOS.
- My Xorg.0.log has libinput-errors (see below)
- My monitor usually uses a refresh rate of 144Hz. Reducing it to say 120Hz stops every flickering. Returning to 144Hz also returns flickering.
Things I tried
- Searching the internet and the EndeavourOS-Forum. Most solutions point at the driver (mostly nvidia but I have an amd gpu) or the HDMI-cable. However I don’t think that the cable is the problem here as I have experienced flicker-free experience on other distributions/windows.
- I have reinstalled my GPU-driver, mesa, AMD-firmware and everything I could identify to be related to my GPU or Xorg.
- Changed and reinitialized the Kernel (standard & Zen).
- Changed the Compositor from OpenGL 2.0 to OpenGL 3.1
