this system has a single DIMM which was provided by framework: DDR5-5600 - 32GB (1 x 32GB) memory vendor: A-DATA Technology speed of memory: 5600 MT/s amount: 32 GB channel configuration: single uefi version: 03.03 see below[2] for more details > What you do to trigger it, etc. Various symptoms appear triggered by different things. The suspend/resume issue (which sounds like it is fixed) causes either the completely white screen or the white screen that flickers. Most graphics-related issues that I see on this machine either happen immediately on first boot, or after a suspend/resume cycle, or don't appear to have a trigger. On my most recent boot, my screen flickers in the upper left and lower right corners as a wide rectangular bar, this started immediately after passing the GDM login screen. Another symptom[1] that I experience on this machine (that is probably unrelated) is that heavy firefox usage causes firefox latency to become unusably high - and CPU usage remains low. Restarting firefox temporarily resolves the issue. This behavior started to happen after I switched to X11.
