2D Exporting creates blank screen

...What can be wrong?

OpenGL support of the driver of your graphics card.

try if disabling the SU hardware acceleration (= OpenGL) allows to export correct raster files.

Still, kadir, it is only a sign that there is something wrong with your system! You should check and update your video driver to see if it works because with HWA off, your SU will be less responsive.

Or at least keep it on and only turn it off when exporting.

Yes, it is okay after disabled opengl acceleration. Thank you very very much.

Are you on a Mac? SU on Windows doesn't use HW GL, so it
should not matter if you turn on/off HW GL.

Now it's time to know that!
Why is the setting there then?

SU does of course use OGL under Windows also, what else

Thus a video card w/ a reliable OGL support is important for avoiding the dreaded screen and printing output glitches regularly mentioned by SU f. Windows users again and again using 'gaming accelerated' video cards as e.g. the ATI Radeon series.

I should rephrase, Win SU does not use hardware OpenGL for image export, it uses Windows software OpenGL. It only uses HW GL for screen display when HW GL is selected.

OK, thanks for the rephrasing. Yes, I knew about the export difference so I was quite surprised when misunderstood your first statement!
