I am using IRONCAD that gives you an option to use DX9, OpenGL and OpenGL2. DX9 settings for trouble free operation and OpenGL or OpenGL2 but my Sapphire Nitro R7 370 4 GDR5 and annotation goes on and off. To get it back set to OpenGL2 from DX9 to display the annotation. Is it my card or a DX9 driver fluke. On the first image it shows the annotation box blank, if I resize it will display the annotation. However when the file is exported as dwg, It displays on the autocad viewer.
