I temporarily solved a crash-on-startup issue, as described in this post. However, after about 20 minutes of use, my display has stopped refreshing. I must do a quick zoom in/zoom out in order to get the refresh to occur.
An example would be creating a new solid colour layer. The new layer is visible in the layers palette, but the image has not updated. I can go and hide all layers, turn them all on, and nothing changes on the image display. If I do a quick CTRL+ / CTRL- then I see the change.
A restart of the application solves the issue. Is there a GPU memory leak perhaps? I'm using latest nVidia drivers for GeForce 9800M GTX/SLIe
