Description Sayan Chakroborty 2020-10-23 10:46:30 UTC

Application: kamoso (20.08.2)

Qt Version: 5.15.1
Frameworks Version: 5.75.0
Operating System: Linux 5.9.1-zen2-1-zen x86_64
Windowing system: X11
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:
I opened effects list for the first time after launching kamoso and then closed the list. Then I try to reopen the list and Kamoso crashes with segfaults. This behaviour stays same regardless of whether any effects have been changed or not after opening the list for first time.

The crash can be reproduced every time.

kamoso (22.12.3) using Qt 5.15.8

Same as other submitters, I opened the effects drawer, selected an effect, closed the drawer, then attempted to open the drawer again. At this point the application crashed with a segfault.
