Subject: [PULL 10/19] ui/sdl2: Grab Alt+Tab also in fullscreen mode
Date: Sun, 28 May 2023 17:20:07 +0400	[thread overview]
Message-ID: <20230528132016.3218152-11-marcandre.lureau@redhat.com> (raw)
In-Reply-To: <20230528132016.3218152-1-marcandre.lureau@redhat.com>

From: Bernhard Beschow <shentey@gmail.com>

By default, SDL grabs Alt+Tab only in non-fullscreen mode. This causes Alt+Tab
to switch tasks on the host rather than in the VM in fullscreen mode while it
switches tasks in non-fullscreen mode in the VM. Fix this confusing behavior
by grabbing Alt+Tab in fullscreen mode, always causing tasks to be switched in
the VM.
