Fading coloring from solid to scratchy.

Hi! I am not sure why this is happening but when I have solid colors in a board they all of a sudden turn scratchy unless I merge all the layers (its driving me insane) and it wasn’t doing this an hour ago. Attached are images below! Any help is appreciated



Hello, your screenshot is too small and too vague to see the problem you are talking about.
Is your computer a laptop or a desktop computer? What is the model of the graphics card?
If it’s a laptop, have you ever tried to right-click on the desktop of the computer and select: Run with graphics processor - High-performance NVIDIA processor to run SBP software?
