[Qemu-devel] [PATCH] -show-cursor switch to inhibit SDL hiding cursor.

["andrzej zaborowski" <balrog@zabor.org>]

[-- Attachment #1: Type: text/plain, Size: 249 bytes --]

Systems with touchscreens usually don't display a cursor (in fact they
can't know where the stylus is if it's not touching the screen in this
moment) so it makes sense to not hide the host's mouse cursor even
when grabbed. Only SDL.

Cheers,
Andrew
