I have similar problems since the last AMD Radeon update 21.1.1 (AMD Ryzen 7 5800x, GPU 6800XT). Sometimes the right or left lens flashes when looking left or right. This is independent of the glass cockpit, as I have this with other aircraft as well. Also crashes without error messages are increasing again since the driver update. Therefore I suspect that this depends on the driver(s). Since you have a 3090, you may have updated your driver as well. I’ll wait for the next updates from AMD and MS.
