Krita crashes when I click on the frames in the animation timeline. Sometimes the first click, sometimes after a few. This happens with projects with keyframes and pictures without any frames. This started happening after I updated to 4.3.
I'm running OSX 10.14.6. I have some crash reports if those would help.

Thanks in advance!

* Does this also happen if you reset Krita's settings? (https://docs.krita.org/en/KritaFAQ.html ... figuration)
* If you start krita from Terminal.app (run /Applictions/krita.app/contents/macos/krita), is there anything interesting printed to the terminal?

I tried both suggestions but to no avail reset the settings with no change and the terminal didn't print anything after opening the program.
After a little more digging, I did find that the cause of the crash seems to be dragging the mouse along the timeline - not clicking.

@Leonardo can you please read the description of a similar problem here: https://bugs.kde.org/show_bug.cgi?id=424037 and check if it's the same problem as you have? Both yours and theirs are crashes and related to animation timeline.

@tymond, @boudewijn:

I see this with the 4.3.0 appimage with three different (various lengths/sizes) animations that have previously shown no problems on Debian Stable.
It happens as soon as I click on a frame or, if not, when I try to click on another frame or if I try to scrub along the timeline.
A fresh kritarc file and fresh resources don't fix this.

Example terminal output:
QPainter::begin: Paint device returned engine == 0, type: 3
QPainter::setCompositionMode: Painter not active
QPainter::begin: Paint device returned engine == 0, type: 3
QPainter::setCompositionMode: Painter not active
QPainter::begin: Paint device returned engine == 0, type: 3
QPainter::setCompositionMode: Painter not active
Segmentation fault

The animations play ok but crash if I then try scrubbing along the timeline.

Later, when I have free time, I can try Windows and Ubuntu and other variations to check for any differences, similarities, patterns etc.
I'm sure that I've tried these animations before in 4.3.0 with no problems (but I don't keep records of every little thing I do).

@Leonardo: Can you check and ensure that Canvas Graphics Acceleration is turned on?
I find that a crash can be induced in 4.3.0 onwards if you scrub in the Timeline with it turned off.

This doesn't seem to affect mine - crashing with it on and off.

This seems to be it. Thanks!
