Maybe you can help me with the following.
In windows 8, 10, 11 there is a white lightning flash when you open a folder window. It is not there in windows xp and windows 7. You can only see the white flash when darker colors than white are used in the windows theme!
When a folder window is opened then windows 10 starts to build the colors of that window, it starts with white! In xp when you open a folder on the desktop it just starts with the color of the background of the desktop. But in w10 it starts with white. Not everybody notices it because a lot of people use the original theme of windows and in that case almost everything is white. The problem is a bit solved when the windows animations are all on but I don't like those irritating animations. Even now when people start using black themes microsoft hasn't done anything to change this. It seems hard coded in the product.
Link to a youtube movie made by someone where you can see that it starts building the window with white.
