Nothing like you describe happened. I would guess, you used upscaling post processing shader in 3D game which is pointless and in older versions they weren't even working.
Try changing post processing shader or turn it off completely, and if that doesn't help, restore settings to default(option for that under system settings) as quite a few things changed and old config might be even breaking stuff. But I would bet on post proc shaders since D3D backend doesn't support them at all;p.
