Hello,
Welcome to Microsoft Q&A!
Color Blink Issue at the time of UWP App Resize
We can repro this behavior, and color blink part is a layer(splash screen) of current window, it is rendered before current window's content, so it looks blink when you resize app window. Currently there is no api could set this layer run time.
I saw you used dark theme, for this scenario, you could set splash background as black steps appxmanifest->visual assets->splash screen background-> black
.

It‘s know issue, please pay attention to the following update.
