I have a Raspberry Pi 4 (4GB) that works fine graphically when I remote desktop into it, as soon below enter image description here

However, when I open Firefox or Chromium, I get distorted graphics. enter image description here

Additionally, when I use my Raspberry Pi to Chromecast a video to my smart TV using VLC, the video occasionally gets slightly distorted until a sufficiently different graphical image updates the screen in the stream (as to update all the pixels).

What might be causing these graphical issues?

This worked for me on several Pi4's I have deployed with bookworm:

  1. Add the xrdp user to the ssl-cert group: $ sudo adduser xrdp ssl-cert

  2. Modify the /etc/X11/xrdp/xorg.conf file and change the 'Option DRM Device' line to:

Option "DRMDevice" "" (that's a space, and two double-quotes).

  • This worked very well. It was Option "DRMDevice" "/dev/dri/renderD128" and I changed as you said and things worked fine.
