From e8f1c30c2fdb295adc0a37d0b7b83a1d18b0ad22 Mon Sep 17 00:00:00 2001 From: Kai Koehne Date: Wed, 2 Jul 2014 13:30:38 +0200 Subject: [PATCH] FAQ: Extend part describing OpenGL/Direct3D issues Qt Creator nowadays does a runtime check, and shows a nagging dialog if OpenGL context cannot be created. Also, VirtualBox needs the Direct3D support to be enabled in the Guest Addons, too.
