Resizing Issue with SDL_WINDOW_BORDERLESS on Xorg [SDL3]

[Farouk123456]

Hello I’m learning vulkan and want to create a custom title bar, so I used SDL_WINDOW_BORDERLESS to remove decorations but then resizing got super glitchy i.e. image not updating for seconds I don’t think it’s an issue in swap chain recreation because if I turn on decoration everything works fine also if I run my code in Wayland it works as well its only when using borderless on x11 that I get glitches

here is my code https://pastebin.com/kJmqzVfM

I’m using SDL3 and HitTesting for my window Any help would be appreciated

The issue definitely seems to be in hittesting on X11 if i implement my own resizing it is buttery smooth Maybe i just implemented hittesting wrong ?

Can you provide a link to a full project, so we can build and run it here?

[Farouk123456]

I already did its only that file in the pastebin link Just compile it with clang and it will work

Looked into the SDL code, seems like this should fix it https://github.com/libsdl-org/SDL/pull/7686

Implemented #7686 myself with vulkan IDK why the merger was saying that vulkan doesn't work with it because it works like a charm for anyone who is interested, here is my code:

I believe this is resolved by #7686, which I just merged.
