Description (last modified by vanfanel)

Hi there,

I have recently been using Scummvm (latest GIT code build) on WAYLAND, the new graphics server currently becoming the default on many GNU/Linux distros by now.

The problem is that the mouse cursor in fullscreen mode, when a game doesn't fill the entire screen area, is sticky around the edges.
That happens because the internal cursor position goes beyond the game area, which shouldn't happen.
Scummvm uses SDL_WarpMouseInWindow() to avoid this, which seems to be non-working on WAYLAND, hence the problem happens.

There's also a thread on SDL2 development repository to discuss this Scummvm issue, and SDL2 WAYLAND backend devs apparently think that SDL_WarpMouseInWindow() shouldn't be used:
