Dear Maintainer,

Graphics Controller

It is intel gen 3 and supports GL1.4 and ES2.0.

At Debian (testing) Bookworm this recently was working without problem,
using ES2.0 hardware driver at Wayland and automatically
galamor was disabled and the llvmpipe software driver at Xwayland
wa selected, because version GL1.4 is too low.
The latest Xwayland package now tries to use ES2.0 with glamor at
Xwayland. This causes blackscreen (Java8, Chromium), xeyes and not working
es2_info end glxinfo.

Problem disappears by using environment var: XWAYLAND_NO_GLAMOR=1

I reported the bug upstream for Xwayland:

https://gitlab.freedesktop.org/xorg/xserver/-/issues/1288

It will be fixed.

Hi,

Could you update this bug with its status?
I got the impression that it is fixed upstream, but IIUC the commit that fixed
it is as of yet only in the 'master' branch and (thus) not part of an upstream
released version. But it also seems that this issue resulted in fixes in
several projects? It appears that you were on top of (all the) things, so I
figured it's better to ask you then trying to figure it out myself.

Cheers,
  Diederik
