Reproducing the repaint bug:

Wow! Strange that I'd never done such a thing! Although I can't reproduce the crash that's reported here, I can see that the second folder isn't painted and pacmanfm-qt crashes after I right-click inside it:
This is very bad. I'll look into it tomorrow. |
@agaida I use Arch's Qt-5.11 too. Can you reproduce this bug under Debian? |
it took me several attempts to reproduce this in arch - so just keep clicking - somewhen™ it will not repaint and after a while it will sigsegv - just have to switch to debian and test it there |
OK, this is related to Qt 5.11. I can't reproduce it with Qt 5.10 (on another machine). Damn! In just an hour after I upgraded to Qt 5.11, this is the third problem I encounter (the other 2 aren't related to LXQt and are tolerable). |
Whatever anyone might say, Qt in't backward compatible anymore. grrrrr.... |
To find the cause, I simplify the procedure: (1) Open 2 windows that show your home. Then, a miracle will happen and the contents of the first window will be wiped out. |
we talk about Qt 5.11? I'm not able to reproduce with Qt 5.10 |
Yes. I found the cause but not the cure yet. |
God damn - will it ever be usable before the first or second point release again? :( |
Fixes lxqt/pcmanfm-qt#685 This may be a workaround for a bug in Qt 5.11.
@Exagone313 If possible, test lxqt/libfm-qt#197 with Qt 5.11. It works here. @agaida Please test the same patch with Qt 5.10. |
It fixes the issue, yes. |
@Exagone313 Thanks for testing. It was a regression in Qt. |
Fixes lxqt/pcmanfm-qt#685 This is a workaround for https://bugreports.qt.io/browse/QTBUG-68581.
god damn - closing a bug with a commit to my branch is kind of strange |
