I remember it worked in some older version (maybe it was 1.9.x, I don’t remember the exact version).
I’m using WindowProperties to set the fullscreen/window mode and window size/origin.
I also tried a simple example (like carousel from the samples) with setting fullscreen in Config.prc.
Panda3D crashes in the both ways with:
direct/showbase/ShowBase.py", line 802, in _doOpenWindow
AssertionError: has_size() at line 140 of built/include/windowProperties.I
Panda3D version - 1.10.2, OS - Ubuntu Linux.
I also tried to make fullscreen borderless window with properties.set_undecorated(True), it works, but it’s not much useful because I can’t switch to Panda3D window (with alt+tab), it doesn’t have an icon and I can’t move it between a monitors.
