Upload some details about your video driver using the instructions here: https://drmdb.emersion.fr/

Install libdrm-tests and run modetest, attach the full output of that

run:

echo 0x1FF | sudo tee /sys/module/drm/parameters/debug # Enable verbose DRM logging
sudo dmesg -C # Clear kernel logs
dmesg -w >dmesg.log & # Continuously write DRM logs to a file, in the background
flutter-pi ... # Run flutter-pi again, manually terminate it after a few errors have happened
fg # Kill dmesg with Ctrl+C
echo 0 | sudo tee /sys/module/drm/parameters/debug # Disable DRM logging

and attach the dmesg.log file
