Description

When teleporting the cursor with SDL3 by calling SDL_WarpMouseInWindow(window, x, y) (which is implemented here), the mouse does warp, but the cursor is still also ghosting in its location before the warp. Note that the window is not constantly submitting frames to the compositor (it's not a game).

I don't know the internals of Hyprland, but it looks like there is a region of the screen not being correctly marked as damaged. So every other frame in the compositors swapchain, you get the old cursor show up.

How to reproduce

Make the mouse teleport more than one tile.

You can also see how sometimes the cursor is cut in half when it's ghosting. I'm assuming that's across the edge of a tile (where one tile is marked damaged, and the other is not).

I assume these are software cursors..?

I assume these are software cursors..?

I don't know for sure. I'm on NVIDIA, and after reviewing my config, I see I forgot the cursor:no_hardware_cursors = true setting.

After adding this line to the config, I still see this glitch happening. So now, yes for sure it happens with software cursors, but it might also happen with hardware cursors (I don't even know if that's possible?).

might also happen with hardware cursors (I don't even know if that's possible?).

I'm pretty sure it's not possible thats why I was assuming these arent hw
