Change Details

If hardware cursor support is not available when using the drm backend for Wayland compositing, the software cursor texture will not be updated when the cursor image changes, and it will still be drawn when no cursor image is set (such as when running a full-screen game). Furthermore, the drmModeSetCursor and drmModeMoveCursor functions will still be unnecessarily called when the cursor is moved or hidden. To correct this, the drm backend should emit the Cursor::cursorChanged signal when the cursor is updated if using a software cursor and the compositor should check if the cursor is hidden and the software cursor image is not null before rendering it. DrmBackend::moveCursor and DrmBackend::hideCursor should also return immediately if using a software cursor.

Furthermore, the drmModeSetCursor and drmModeMoveCursor functions will still be unnecessarily called when the cursor is moved or hidden. To correct this, SceneOpenGL should connect Platform::cursorChanged as opposed to Cursor::cursorChanged to its texture update function, as only the former will be emitted when the cursor is updated and the compositor should check if the cursor is hidden and the software cursor image is not null before rendering it. DrmBackend::moveCursor and DrmBackend::hideCursor should also return immediately if using a software cursor.
