[Qemu-devel] [PULL 4/4] ui/gtk: fix cursor in egl mode


From: Gerd Hoffmann
Subject: [Qemu-devel] [PULL 4/4] ui/gtk: fix cursor in egl mode
Date: Mon, 12 Nov 2018 16:15:16 +0100

In egl mode the scale_x and scale_y variables are not set, so the
scaling logic in the mouse motion event handler does not work.

Fix that.  Also scale the cursor position in gd_egl_cursor_position().
