No preview during scan, flickering preview when idle

[PaddyCube]

Hello,

I run the latest version and got some trouble with preview images I hadn't before.
When scanner is in idle (--READY--) state, preview image gets shown but switches between real image preview and a black (empty?) image. It changes approx every 0.5 second.

When running a scan, it doesn't show any preview. I verified that the last taken image gets stored as preview.jpg, but it doesn't show up. This is odd as I can't see, if the image set will become good or not during process.

Any chance to fix this?

My mistake, I use a different setting (larger kind of scanner) and this brokes the preview image. I was able to fix it now.
