Random crash on window resize.

YouDoItWrong

Hello. I am integrating Urho3D into Qt. But I am stuck with weird bug. When a window is resizing application can randomly exit. I made a short video about this problem: https://youtu.be/6d7mBhbmT7U

Is It Qt internal problem or I did something wrong? Can someone give me advice/recommendation about workaround or fix? Thanks in advance.

Chris Kawa

It seems to have something to do with animating a docking area resize.
Can you check if setting animated to false fixes it?

Christian Ehrlicher

This sounds like https://bugreports.qt.io/browse/QTBUG-64375 - did you check with 5.13.x as suggested in the last comment?

YouDoItWrong

@Chris-Kawa @Christian-Ehrlicher

setAnimated(false); does not help at all.
Qt 5.13.1 from qt.io binaries still crashing here is stack trace:

But I want to keep the possibility to render while resizing the window. So, does this looks like Qt internal bug and I should create a bug report?

@YouDoItWrong said in Random crash on window resize.:

Qt 5.13.1 from qt.io binaries still crashing here is stack trace:

Does it crash also with the testcase provided in the bugreport? If not it would be nice if you can provide a small testcase to this bugreport so we can investigate it.

@Christian-Ehrlicher
By "bugreport" you mean code and error in this "head topic forum post"? If yes then yes :).
I used the same code to reproduce this error with Qt 5.13.1. Basically the problem can be discribed as: SDL 2 window ebededded into Qt with enabled repaint on resize (on SDL side) lead to application crash. If u need a build instruction or some other information how to reproduce this crash, please let me know.
If no - please let me know what do you mean?

No, bug report in Qt bug tracker: https://bugreports.qt.io/secure/Dashboard.jspa
