After the gem window has been resized, hardware-acceleration gets lost. At least, that's what I'm guessing because suddenly Gem runs at 5 fps and cpu goes to 100%. This is an nvidia card, btw.

However the only way to resize the gem window (properly) is using the resize message which (at least for me) does not work properly. (my fix was to hack the source and recompile with the desired default size)
in which way it did not work properly ?
