I just started having this issue a few minutes ago and it’s effecting all my projects where in the game window all my models are flickering and giant spots are vanishing. Also random grey areas are flickering on the ground. Seems like my graphics card is freaking out but it only happens in the editor window, whenever I run my game all the graphics look perfectly fine and nothings running haywire. I can’t figure out what started causing this to happen ? After this happened I installed the new unity update and this did not fix it either. Anyone know what it could be or how to fix it ?
My guess is that you have a drivers issue, for obvious this might be. It’s quite probable that the editor is using a different driver than the game to render the scene.
I suggest you download your latest video drivers, use your video card driver uninstall utility to clean the drivers, reboot, and install the new ones.
