--- Comment #42 from Olivier F. R. Dierick o.dierick@piezo-forte.be --- I have the same issue on a computer with NVidia 9800 GT. The alt+enter workaround did work twice and then I couldn't get it to work again. When the workaround did work the 3D rendering was completely broken.
On the GTX970 machine, the workaround works most of the time, and the rendering is correct.
