Rhino Pixel Bug?

Hi everyone,
I’m using Rhino 6 in free version. I have studies in 65 days without truble but today the file got too loaded then crushed and buged (ı guess) somehow. Before the colors, lines and texture were clear but now (after crushing) all my surfaces are in pixel, textures are over-scaled and some textures are not renderable, lines are not straight (like pixel by pixel) I’m adding some photos to clearify my problem. Please help me, I ma using it just for 2 months.

can you run the systeminfo command in rhino and post the results here please?

Hello - you should at least reboot the machine, and possibly, reinstall video drivers.
