I have already reported this exact issue on Series X with the flashing and strobing textures (rapidly flashing on and off, not staying loaded in).
Please report this via ZenDesk as well, otherwise, I fear it may not get fixed for a long time. It’s been reported since the game launched and happens in both the beta and public build.
After the last update, I no longer see the flashing textures. BUT, whatever fix was done, it had caused my avionics to fail completely on the inibuilds A320. The screens do not turn on at all now. I loaded my flight plan in the efb on the main menu after setting it up on the msfs flight set up page online. I load into the game and get into the air craft. No avionics. What I was most excited about in 2024 os now gone.
