win11 with custom titlebar/no titlebar maximize covers taskbar.

[yatli]

Windows is doing its (too) smart and backward compatible thing here. Maximized window is sucked a few pixels into the boarder of the display, and is hanging over the taskbar.

Must work out a fix because not everyone has the option to go back to win10...
Possible workaround: show system titlebar before maximize, keep track of the window geometry, hide titlebar, then restore geometry.

Update: this only happens when the maximize is triggered via win+up.
Double clicking the title bar, or clicking the maximize button works as expected.
