Though this may not matter, as I thought the xrdp implementation
mostly ignored the GPU anyway?
That may no longer be the case, of course...

OK - RDP, this may be important.

If you log in locally, it works "normally" in both single-buffered and
double-buffered modes? Or only in one of the modes?

But via RDP it always fails?

What mode is your xrdp running in? Is it xorgxrdp mode or is it
VNC-forwarding mode?

TBH, I'm not a huge fan of RDP, even between Windows machines, as I've
had it do weird stuff to me on many occasions.
For remoting to a Linux box I always prefer X11 "natively" (there are
adequate Windows-hosted X11-servers now, or WSL2 can do it) or VNC,
because they bite me less often.
But none of them Just Work all the time...
(between Windows boxes, VNC usually works...)
