Auto maximized blank empty white window (no ui) on resolution change (fixed w/ Qt v6.7.2)

[graphixillusion]

qBittorrent & operating system versions

qBittorrent v4.5.3 lt2,0.9 and qt6 official build, Windows 10 22H2 x64 build 19045.3031 (10.0.19045)

What is the problem?

I use nomachine for remote connecting to a machine with qbittorrent running on it. I usually have qbittorrent minimized and running in the systray. When i log in again with nomachine which dinamically adapts the remote display resolution according to the client specs, i have a maximized qbittorrent window on top of everything (blank, white, no ui is showing, just the top bar). So i need to minimize and maximized it again for make it works. Another information if it could help understanding the problem is that if i try to close the grayed out window, qbittorrent crash instead close it to systray as it shoud when it works correctly.

Steps to reproduce

1. qBittorrent is minimized in the systray;
2. Lock the PC;
3. Disconnect the remote session with nomachine;
4. Connect again to the PC with nomachine;
5. Unlock the PC;
6. qBittorrent maximized window is on top of everything (blank, whithe, no ui, seems freezed). In this state if click on the x to close the window ---> crash

You mean that it becomes like this?

[graphixillusion]

@Legendarion yep, right. This window auto showing up and the only thing you can do is minimize --> maximized again. If you try to close, the program crashes.

If you try to close, the program crashes.

Any stack trace/crash report?

[graphixillusion]

@xavier2k6 in the log there isn't any error. This issue seems to occurr only in the qt6 build. I've just tried the qt5 build and it works good.

Any stack trace/crash report?

My client shuts down correctly, no crash occurs.

4.5.4 with qt 6.4.3 doesn't have this problem, so it's definitely a qt 6.5.x problem

Qt 6.7.2 fixes this issue. @graphixillusion @Legendarion @Milincho can you confirm?

[graphixillusion]

Yep it seems fixed.

@Legendarion yep, right. This window auto showing up and the only thing you can do is minimize --> maximized again. If you try to close, the program crashes.

Not that matters anymore, but just to clarify: it's not "crashed" if you close it when it's blank.

When the UI is not showing, the setting for "close button minimize the window" would also NOT in effect. Therefore, closing close button would exit QbitTorrent.

Qt 6.7.2 fixes this issue.

@qbittorrent/bug-handlers Raising Qt minimum may need to be looked in to again.
