As a workaround use the breeze window decoration. *** This bug has been marked as a duplicate of bug 361236 ***
I'm already using breeze window decoration. It prevents ImageWriter fromm crashing kwin, but others still do when opening additional windows.

But in this bug (375389) breeze-dark window-decoration is used.
(In reply to Peter Wendel from comment #4) > But in this bug (375389) breeze-dark window-decoration is used. no this bug is not about breeze. Your initial comment clearly shows a backtrace of aurorae. If you have an issue with breeze: report a new bug. No dev can understand that you are talking about a breeze bug in a report clearly about aurorae.
You marked it as duplicate. I only used your kde-tool for reporting a bug. So this is a new bug with brezze but the same behaviour of kwin as in aurorae. It quite seems something is wrong with kwin not with any kind of decoration, when this happens in breeze and aurorae.
This is a technical bug tracker and in order to fix bugs we need to keep to some rules. One of the rules is "one issue per bug report" another is "the issue is described in the first comment". You reported a crash through our crash reporting tool. This crash is in Aurorae. Thus this bug report is about the issue about aurorae and nothing else. If you want to report another issue, please report a new bug. For us developers it's impossible to manage bugs if reports are about multiple and different issues. Please understand this. We get every day for KWin about 5 new bug reports. One of our main task is just to manage them. Fixing happens at a different time. In order to fix bugs the reports need to be in a high quality. They must be precise. A developer must be able to look at it and understand where the bug is. If a bug report mentions multiple issues in different areas it's not possible. In this specific case: a developer will look at the first comment, see the well known Aurorae issue and move on. So I kindly ask to leave this bug report as a duplicate and to report any other issue as a new bug report. *** This bug has been marked as a duplicate of bug 361236 ***
