sample-app

There is some regression in handling of window position/size changes from
WinApi e.g. using SetWindowPos or MoveWindow. I attached source code of a
simple app that does not work as expected for me in Wine 6.0-rc4. The same app
works correctly when run under Wine 5.12. I'm testing in Linux Mint 20 (Xorg).
> From my experiments (see sample app) it seems position/size set using

SetWindowPos or MoveWindow is ignored unless window is hidden or window style
is changed after window creation and SWP_SHOWWINDOW flag is not used.
I discovered the bug when using the windowed mode in the Dash Faction mod for
the Red Faction game. It regressed some time ago but unfortunately I don't know
exactly when.

The sample application works for me, with wine 6.0-rc4 and KWin 5.20.4. What
window manager are you using?

Linux Mint).

I wonder if this is related to what I experienced after upgrading to wine 6
also in Linux Mint with Muffin, described at
https://forum.winehq.org/viewtopic.php?f=8&t=34823
I found that the issue depends on the window manager: "Mutter (Muffin)" in Mint
Cinnamon and "Marco" in Mint Mate and Ubuntu Mate.
In Mint Mate you can switch the window managers and the issue manifests or not
depending on the WM.

I bisected it to commit c5ec1585f6e5211a2b63e3435748210552250534:
winex11.drv: Always update _NET_WM_STATE in update_net_wm_states().
