@@ -60,6 +60,7 @@ Other Changes:
- Backends: SDL2,SDL3: avoid using the SDL_GetGlobalMouseState() path when one of our
window is hovered, as the event data is reliable and enough in this case.
- Fix mouse coordinates issue in fullscreen apps with macOS notch. (#7919, #7786)
- Essentially a working for SDL3 bug which will be fixed in SDL 3.3.0.
- Better perf on X11 as querying global position requires a round trip to X11 server.
- Backends: Win32: minor optimization not submitting gamepad io again if
XInput's dwPacketNumber has not changed. (#8556) [@MidTerm-CN]
