Unsolved Qt 5.12 Release Combo Box -> Bug! Bug! Bug!
-
@X-Crack can you create a minimal example out of your program? Otherwise its hard to find the origin of the problem.

Sorry, my project is complicated to build.
I am a statically compiled QT source code.
But the problem is already very clear.
I believe that more people will react to the same problem in the near future.This kind of problem can also be presented in the official installation package given by "Qt Creator".
You can try it!

This is something you should have said at the beginning!
You're not using official build.
My guess is that you're missing the correct style in plugins/styles.I just tried on my Windows 10 machine with Qt 5.12 MinGW - it looks like it did before. So, I cannot reproduce your issue.

Sorry, am I the only one that doesn't see what the alleged bug is?

@VRonin
I also wondered that. Maybe that dropdown list is slightly offset
in the "bad" example. -
@mrjj No, I think it is how it looks: it looks like old style Windows theme (Windows XP/2000). Simple screen-shots without animations would be better...

Ahh, Good Catch. I was focusing on excessive open/close :) -

Please check this video, the official original file also has a bug

Please start the program, reproduce the bug, and while the combo is doing whatever it isn't supposed to do click "pause" in the debugger. Then extract the stack trace(s) and upload them for us to inspect. It's impossible to tell what's going on without any information about what's being executed (i.e. no source, no stack).
Every time I click on the drop-down box "Combo Box", I start a thread.
Why do you do that?
PS
Ah okay, I understand now what the problem is. I have no idea why you get that. My advice is to try it as follows:
- The precompiled packages that come from Qt Company
- In a clean virtual machine. Also one that's not localized.
- Finally if 1 and 2 fail, try with a localized virtual machine
If it's present in case 1, 2 or 3, then I'd suggest filing a bug report on the tracker.
