Jitter/noise in document scan

[Gerard van Drielen]

Ubuntu 21.04
Documentscanner 3.38.1

When using the documentscanner about 10 times, without restarting the app, closing the previous scan (delete button), starting a new scan everytime, the background window (white) shows jitter/noise (in black) which will stay there every next scan. It may even become worse.
The noise become part of the actual scan too!

You will have to stop the app and reconnect the scanner.

I've noticed this problem to be reproducable.

See attached screen output.

Kind regards,
Gerard van Drielen
