Pixelated Transparency

[Anonymous]

I've just started at a new office, and my computer seems to be having issues with transparency in Revit, I assume, anyway. When I select any element, it appears pixelated, and now in a 3D view the curtainwall is also pixelated, images attached. Is this a graphics card issue? It is isolated to me, others don't have this same issue.

Thanks for any advice offered!

Thank you for your posting @Anonymous. 

Have you tried to turn off Hardware Acceleration? Go to R button > Options > Graphics tab, and uncheck the options and see if this persists.
