Qt 6.6.0 Windows Unable to set geometry Issue

[ollie-dawes]

Tested out framelesshelper width Qt 6.6.0 today and I see the following issue. If you run the quick or widget examples and drag the window to a second monitor then the window will fail to resize and you will be left with a incorrectly rendered space at the bottom of the window which is suspiciously the same size as the title bar.

Quick window after moving to second window:

The widget example will fix itself after about a second but the quick example requires you to resize the window for the issue to go away.

The following warning is logged every time I move the window between monitors:

[2023/11/11 13:31:44.170] <WARNING> QWindowsWindow::setGeometry: Unable to set geometry 160x600+1200+620 (frame: 176x608+1192+620) on ApplicationWindow_QMLTYPE_2/"" on "DELL U2715H". Resulting geometry: 160x631+1200+589 (frame: 176x639+1192+589) margins: 8, 0, 8, 8)

Note that the issue does not present it self if I switch back down to Qt 6.5.0.

Qt 6.5.3 & 6.6.0 has bug which is fixed in later versions: 6.5.4 & 6.6.1. This is not a FramelessHelper bug.

I can't "fix" this bug because it's very hard to workaround, please downgrade your Qt version or build a newer version from source yourself.

Gotcha, if this is a Qt issue then feel free to close.
