Bug#1037045: blobandconquer: fails to start with Xwayland: Couldn't set 800x600 video mode: Couldn't find matching GLX visual

[Simon McVittie <smcv@debian.org>]

Package: blobandconquer
Version: 1.11-dfsg+20-2
Severity: important

To reproduce:

* GNOME 43 in its default Wayland mode, with Xwayland available
* either of:
    * "classic" SDL 1.2 (libsdl1.2debian version 1.2.15+dfsg2-8 tested)
    * sdl12-compat (libsdl1.2-compat-shim version 1.2.64 tested)
* run blobAndConquer

Expected result: gameplay

Actual result:

[DEBUG (0)] Pak : Filename set to /usr/share/games/blobAndConquer/blobAndConquer.pak

Workaround (1): log out, and log in to "GNOME on Xorg" instead.

Workaround (2): install libsdl1.2-compat-shim *and* run with
SDL_VIDEODRIVER=wayland,x11 in the environment (which is not the default,
even with SDL 2, because it can cause regressions in other games)
