"At the risk of repeating myself yet again (and again and again).....  You are not the only one.  Look down the list of questions before yours and you'll see several others for the past two weeks.  In fact, it's almost always a good idea to try searching first before you post a question that someone else has probably asked. \nSome people who have ATI graphics cards are having the pink problem with the most recent V3 upgrade. It affects any of the newer viewers.  See http://jira.phoenixviewer.com/browse/FIRE-4945 .   For a quick but temporary solution, go to Preferences &gt;&gt; Graphics and disable Basic Shaders.  For a more permanent solution update the 12.1 Catalyst driver from http://support.amd.com/us/gpudownload/windows/Pages/radeonmob_win7-64.aspx?type=2.4.2&amp;product=2.4.2....  or run the AMD driver autodetect tool to update: http://support.amd.com/us/gpudownload/windows/Pages/auto_detect.aspx. Updating your drivers will probably also clear up the funky black lines.  If not, go to Preferences &gt;&gt; Graphics &gt;&gt; Hardware Settings and disable OpenGL VertexBuffer Objects (VBO) \n"
