So just an update, I've been working between 2 builds so far as to track down this issue. I have an Armbian framework built version with Debian Bullseye and the prebuilt latest Armbian Debian Bullseye CLI version. I installed both Xfce4 and LXDE on the framework version and found that XFCE4 has a blur in the same spot every time on the right side of the monitor in the middle of the last 1/3 of the screen. If I log out and launch into LXDE the blur is not present. Even in the Debian CLI version same effect is happening. So for some unknown reason XFCE4 is causing this issue and currently working on tracking down as to what setting or configuration is causing this display issue. If anyone has any suggestions or ideas definitely open to hearing anything at this point.
