Hi,

I’m running into the strange effect that doing a
putenv(SDL_VIDEO_WINDOW_POS, “x,y”) moves the window to the position
wanted but also moves all content in the window by an equal amount in
the same direction. This is on a mac. All content is generated using
opengl (if it makes any difference).

The same program works perfectly on windows. Also, the window positions
are different: y=0 is at the bottom of the screen on a mac and at the
top in windows.

Tested with SDL 1.2.11 and 1.2.13. The relevant code is here, in
SDLDisplayEngine::init (sorry, no small test .exe):

https://www.libavg.de/websvn/filedetails.php?repname=libavg&path=%2Ftrunk%2Flibavg%2Fsrc%2Fplayer%2FSDLDisplayEngine.cpp&rev=0&sc=0

Am I doing something wrong? Is there any workaround?

Cheers,

~ Uli
