Description Richard Hornby 2022-05-12 15:06:55 UTC 
Application: kstars (3.5.8 Stable)

Qt Version: 5.15.2
Frameworks Version: 5.78.0
Operating System: Linux 5.15.32-v8+ aarch64
Windowing system: X11
Distribution: Debian GNU/Linux 11 (bullseye)

-- Information about the crash:
- What I was doing when the application crashed:  I was switching out of scale or zoom view in video when EKOS crashed.  I am on a RPi 8GB which was at 66% memory, 80% CPU, temp 56deg, fan on.

This repeated a couple of times and may be related to overall resource availability.  In similar situations I have had the whole pi freeze.  However, this has happened in EKOS 3x without the pi crashing.  Am running in Debian 11 Bullseye 64bit.

The crash can be reproduced every time.

-- Backtrace:
Application: KStars (kstars), signal: Segmentation fault

Hi - tks for the new build!

Updated to Build: 2022-10-25T08:32:02Z  Stable release.

KStars no longer crashes when the Reset Frame button is pressed.  However, pressing the button doesn’t seem to do anything.  

eg: in the Indi Control Panel for ASI462MC, Image Settings Tab, set Frame to 600x600 and start Stream.  

Video viewer in Stream shows image 600x600.   

Press Reset button - it turns Orange but nothing happens, the video freezes for a couple of secs and continues at 600x600.

Re-enter Control Panel, stop Stream, set frame to 900x900, start Stream, video runs at 900x900.  

Press Reset button, same as above.  

So the system is usable, does not crash, and will swap resolutions providing the Stream is stopped while doing so, but I cannot tell what the Reset Frame button is doing.  

A suggestion is that the button should either return to full frame, or return to the Image Settings Tab to allow for resetting the Frame.

Best

R
Comment 4 Richard Hornby 2022-10-26 22:10:34 UTC 
Sorry.  I had forgotten the way to zoom in the window - ie to draw a box round the desired ROI.   When the Reset button is pressed, the window reverts to full size.  

Looks fine and FIXED to me.  

Thanks
