The driver was updated to 27.20.100.8336 for a Intel UHD Graphics 620 card so to improve the running of SolidWorks, but now the DraftSight graphics is all corrupted? The graphics were fine with the older driver but reluctant to wind back as SolidWorks is better! This card supports OpenGL and DirectX at versions above the recommended version for DraftSight, so can you advise a) should it work, b) does some setting need changing or other? A video is attached of the graphic corruption. Thanks
