From 875de90ff8ecdad69fa8ffe76e39ba5da8d2dc2d Mon Sep 17 00:00:00 2001 From: Yoann Lopes Date: Tue, 17 Sep 2013 17:00:28 +0200 Subject: Fix QVideoSurfaceArbFpPainter mistakenly failing to start in some cases. If an OpenGL error occurred before starting the video painter, it would fail to do so. This patch simply makes sure the OpenGL error flag is cleared before checking for GL errors that would occur in QVideoSurfaceArbFpPainter's code.
