Update: Above is not entirely true. If you start the game with a fresh PIUPRIME.INI config file by simply deleting your old one, the game goes into 640x480 in a window on desktop.
Comparing the executables F2 to Prime, the devs added some more code for handling 1280x720 mode which uses some X11 specific features to do...something. This code is located in a function that calls XCreateWindow. This is controlled by two factors:
- SD/HD mode switch in
PIUPRIME.INIfile which can be modified via the operator menu - If the screen's height is greater than 719, e.g. the currently configured resolution of the screen supports at least 720p If both above are true then do all the fancy magic to switch resolutions with X11.
This needs further investigation how it's done in order to create proper blocking code for desktop machines to run the game properly in window mode. Fortunately, there are just a few new functions added to run the screen resolution switching logic, so the scope is rather small.

The game always goes to fullscreen no matter what and messes up the desktop. It switches to the native resolution but does not show the content of the render window but the desktop in the changed resolution. Furthermore, the game is a bitch and grabs the keyboard which does not allow us to exit it on the same xsession anymore. So we have to get rid of that keyboard grabbing, first. Then, figure out why the game does not properly window.
