When playing with sdl2 via pysdl2 I noticed this strange side-effect where once the sdl script runs unrelated windows which would normally become translucent when moved do now stay opaque.
I wouldn't mind all that much if it weren't for the nagging feeling that this indicates that I'm doing something fundamentally wrong.
Anyone able to enlighten me as to what the heck is going on here?
Here is my script:
import sdl2
import sdl2.ext as se
import time
def main():
k = 2
event_buffer = (k * sdl2.SDL_Event)()
se.init()
window = se.Window("what the ?", size=(400, 300))
window.show()
while True:
window.refresh()
time.sleep(0.01)
sdl2.SDL_PumpEvents()
sdl2.SDL_PeepEvents(event_buffer, k, sdl2.SDL_GETEVENT,
sdl2.SDL_FIRSTEVENT, sdl2.SDL_LASTEVENT)
for event in event_buffer:
if not event.type:
continue
elif event.type == sdl2.SDL_QUIT:
se.quit()
break
else:
pass
event.type = 0
else:
continue
break
if __name__ == '__main__':
main()
And here are a before and an after screen grab:
The System Settings window of my KDE 5.45.0 desktop without the sdl script running, showing the relevant setting Desktop Effects>Translucency. Notice how the window is translucent because I'm dragging it while taking the picture.
The same but with the sdl script running. Notice how the window despite my vigorously dragging it stays stubbornly opaque.
