Bug#657056: libsdl1.2debian: messes X environment when starting SDL app/game in fullscreen

[01]

Package: libsdl1.2debian
Version: 1.2.14-7

Hello,

This problem doesn't happen with version 1.2.14-6.4, and happens since
the recent 1.2.14-7 update.

Happens with games like OpenArena or Xonotic (its xgl version runs
fine, not the SDL one), didn't try others.

There is already other similar bugs in DBTS but they are related to
previous versions of libsdl.

So the symptoms are when starting the app, we notice some
brightness change to dark then bright again. Focus is given to my
desktop environment and I can't interact with the app, so it's unusable
and may switch back from desktop/app indefinitely.
Killing the app restores the situation.
Symptoms are slightly different depending on the window manager I use.
When quitting the app, happens I have a black
screen from which I can't do much but CTRL+ALT+BACKSPACE.


I thought it could be related to this change:
* XRandR support is disabled by default because it causes desktop
reconfiguring. It can be enabled with the SDL_VIDEO_X11_XRANDR=1
environment variable, or by applying this patch:
http://hg.libsdl.org/SDL/raw-rev/8ec3036098df

But running the app with:
SDL_VIDEO_X11_XRANDR=1 /path/to/app
... didn't seem to help.

Temporarily switched back to previous lisdl version as a workaround.
