at the start of ManiaPlanet, there is first a black screen with a white rectangle in the upper left corner.
Apparently ManiaPlanet is always started first in a window, which is then resized to fullscreen or window fullscreen, depending on the settings.
Using ManiaPlanet_Logs.exe, I was able to set the execution window mode to "Maxmized",
and then a white screen appears before it turns black to show the game login menu.
But I was not able to do the same for ManiaPlanet.exe.

Hint for the developers, in the logfiles I can see a difference...
Window execution "Normal":
Window exectution "Maximized":[Gbx] Window created
[Input] DirectInput initialized. 2 devices found.
Window exectution "Minimized" (doesn't work at all btw.):[Gbx] Window created
[Win32] WM_SIZE=MAXIMIZED(2 560x1 378)
[Input] DirectInput initialized. 2 devices found.
Surprisingly the "maximized" window is only 1378 pixels high, not 1440 as it should normally be with my screen...[Gbx] Window created
[Win32] WM_SIZE=MINIMIZED(0x0)
[Win32] Minimized
[Input] DirectInput initialized. 2 devices found.
