From efc9064e7282aab65b281738089245c229c2df45 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Wed, 4 Sep 2013 18:25:30 +0300 Subject: [PATCH] drm/i915: Fix cursor visibility check with negative coordinates MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit When the cursor x coordinate is exactly -cursor_width, the cursor is invisible. And obviously the same holds for the y coordinate and cursor_height.
