Description Rainer Finke 2018-06-24 13:40:59 UTC

If I start nexuiz (nexuiz-sdl) on Plasma-Wayland the input is not recognized until pressing for 3 seconds the ESC button (XWayland).
Usually I can start the game and select with the mouse e.g. a single player tutorial, but once the actual game starts, I cannot move the mouse anymore.
Sometimes when I start nexuiz, the mouse pointer is already locked in the main menu and I cannot move the mouse anymore. If this is the case, I can at least immediately use the mouse once starting a game.

[server] Send frame event instead of flush on relative pointer motion

Summary:
This solves for me not working relative pointer motion with grab/lock in
Xwayland applications.

Looking at the Xwayland code it is clear, that it expects a frame event on
wl_pointer versions 5 and above after relative motion events. wl_pointer
version 5 support was added to KWayland in b6bd28ab.

If the cursor is locked no absolute motion events are sent. In this case to
make sure relative motion events are processed by the client, send the frame
event after every relative motion.

Test Plan: Manually with Neverball in Xwayland mode.
