A minimal example using SDL3
DESCRIPTION
If an application tries to warp the cursor with the PointerWarpV1 protocol
right after destroying a pointer lock, kwin will ignore the warp request
STEPS TO REPRODUCE
1. Build and run the attached main.cpp file (it can be compiled with just `g++
-lSDL3 main.cpp`)
2. Press Space to lock the cursor and then Esc to unlock it on the window it
creates
OBSERVED RESULT
When the cursor gets unlocked it goes back to where it was before it was locked
EXPECTED RESULT
The cursor should warp to the center of the window after being unlocked

ADDITIONAL INFORMATION
>From a discussion i had with zamundaaa on matrix it seems to happen because the
pointer lock is only destroyed when the surface is committed, so when the warp
request is processed the pointer lock is still active
