Fitsviewer crashes when imaging with Altair Hypercam 183c - Kstars 3.5.2

Until recently (since version 3.5.2) the Fitsviewer crashes Ekos/Kstars to the desktop (either in Stellarmate or in Ubuntu 20.04) when taking images with my Altair Hypercam 183c. The first image taken is displayed correctly, but the following images are displayed incorrectly (but correctly saved to disk). After some images (> 5) Kstars/Ekos crashes to the desktop!

- When i disable the Fitsviewer, all Hypercam 183c imaging jobs run without any issues.
- When i use another cam (e.g. ZWO ASI 178mm) everything runs fluently (with Fitsviewer!)
- Kstars/Ekos 3.5.0 -> no issues with Hypercam/Fitsviewer

There was a major bug in FITSView that is now fixed in 3.5.3 Beta (Nightlies). Can you please switch to beta channel and test that?

thumbs up!  The bug is gone in 3.5.3 beta. I have tested it with all my cams and got no issues at all.
The only thing that annoys me from time to time is the exceptional slow download speed my of usb3 qhy-183m camera. The altair 183c is also very slow. Funny, since both cams advertise with their ram buffer for speeding up downloads.
