Colorspace conversion issue on Monado with XRT_COMPOSITOR_COMPUTE and AMD graphics

Apparently, when running Overte through Monado and having XRT_COMPOSITOR_COMPUTE=1 enabled on AMD graphics, the age-old colorspace conversion issue appears again.

There used to be similar issues on SteamVR in the past (though those seemed to be Nvidia specific): https://github.com/vircadia/vircadia-native-core/issues/643 https://github.com/vircadia/vircadia-native-core/issues/1413#issuecomment-968339032 The same issue happens on some streaming VR setups as well: https://github.com/overte-org/overte/issues/698

I cannot reproduce the issue on my system with Intel dedicated graphics, which makes me think it might be a bug in Mesa's AMD drivers. If someone has a working Monado with AMD graphics setup, it would be great if they could test this, with and without XRT_COMPOSITOR_COMPUTE=1.

I run Monado with the compute compositor and I've never encountered this.
