Comment 6 Tim Richardson 2020-02-08 05:04:51 UTC 
I removed Flameshot a week ago, and this problem has not occurred at since then. I also stopped my panel from autohiding. I will re-enable that now. 
I tried both OpenG: 3.1 and 2.0 as the rendering backend, but this is not a factor. 

I can't read the crashreports, but it seems  to be a crash in a qt library which means it shouldn't happen and these configuration changes I am making are probably not very interesting.

Comment 12 Christoph Cullmann 2021-03-08 22:30:32 UTC 
I still think any Qt version below 5.15.2 is unusable for any of our stuff, as the GC is broken. (at least 5.13 and 5.14 I thought)
Comment 13 Nate Graham 2021-03-09 01:39:21 UTC 
Yikes. Do you happen to know of a bug report for that or the Qt gerrit change that fixed it?
Comment 14 Nate Graham 2021-03-09 03:44:49 UTC 
All right, let's say it was https://bugreports.qt.io/browse/QTBUG-84363.
Comment 15 Christoph Cullmann 2021-03-09 08:45:27 UTC 
Yes, there is some commit hash mentioned that should be in 5.15.1, but I would not count on that, I thought really all known stuff was fixed in .2, but perhaps I misremember that.

In any case, in the CI, for 5.14, even the "trivial" JS indenter tests in KTextEditor crash, often, therefore => useless.

Wow. Thanks for the info.
Comment 17 Christoph Cullmann 2021-03-09 17:04:55 UTC 
Btw., just one of the usual backtraces with Qt 5.14.x
