Wayland backend doesn't work properly on KWin

[coffeeispower]

For some reason, aquamarine freezes on KDE and only rerenders when I focus or unfocus the window.

I also tried running hyprland inside KDE and the same thing happens so it's not a misuse of the library

can you post WAYLAND_DEBUG=1 of aquamarine running under kde?

@vaxerski Here's the logs of my app using aquamarine with WAYLAND_DEBUG=1 logs.txt

yeah the frame loop has been fucked for a while... I tried making it exactly the same as our DRM one but it still breaks, atp I have no clue what's wrong there. I've spent over an hour on this. It's fucked under hyprland too fwiw, you need to move the cursor for it to update at a proper speed. If you want to debug this, be my guest...

Wayland's frame events should work exactly the same as DRM's pf callbacks, but apparently something's fucked and it doesn't. Or I am missing some obvious typo. Could be.

Definitely will be, I don't want to be switching to a TTY just to test tibs, it kinda sucks i can't even take screenshots

Can I also make the window become fullscreen when the size matches the screen size?

Also the window decorations don't appear, I think KDE implements server side decorations so I can fix that, on gnome you already know that they refuse to implement server side decorations because they're blinded by ideology

EDIT: Yes, KDE does indeed support server side decorations and this is the protocol: https://wayland.app/protocols/xdg-decoration-unstable-v1#compositor-support

Idk how you didn't spot this mistake like how are you expecting it to render frames when events happen if you're not even telling it to render on dispatchEvents

Also added server side decorations too: coffeeispower@7fe0b6715202
