SDL fullscreen offset Xrandr -o left

Hi,

running an SDL app in fullscreen having my display in portrait mode (using
xrandr -o left), the frames seems to be affected by an offset of hundreds
of pixels. I’ve tried to force an offset through SDL to fix it without
success. It looks like my frame is prerendered into a square surface which
is then drawn on the display (producing then this offset). I’m using SDL
1.2.

Any hint to fix this?
