Bug Description
Binary package hint: xsane
Since the update on karmic I cannot use the preview window in x-sane anymore with my Epson Perfection 2580.
When I start x-sane and select the dummy scan device, it works. But when I select the epson scanner, the preview windows stays completly grey. Moving the mouse on the window displays some edgemarkers, but I cannot see neither use any menubars, buttons or selection marks. It looks like garbish painted on the screen - although compiz is turned off.

I have this problem as well. I am using a HP Photosmart 2610.
I notice it more if I am running picasa at the same time or immediately after switching on printer. Logging off and on again (not simply shutting xsane, completely logging off) and trying again generally works. I can get a similar circumstance by pressing the scan button on my printer which shows an error message on the little LCD and the preview then has problems.
The application remains locked but does eventually become responsive. Once it it is in an invalid state no amount of shutting preview and reopening it will make any difference. No buttons or options appear. If you mouse over the top (say) 5mm and the left edge 5mm show some detail but nothing appears in the centre. The Acquire button does not appear.
My guess is that the scan device is somehow locked by another program and it is not sensed properly by the preview code. It may also be invalid data returned from the device confusing sane.
