Big windows graphics glitch

[lesleyrs]

Hi, I noticed that changing background colours other than the default red one from crates.io example results in messy graphics.

After maximizing it seems to work fine but when you make the screen smaller again rapid screen flashes start to happen.

This happens on windows 10 + intel graphics hd 620 and HiDPI screen, on a different laptop the same code worked fine.

white(same for any other colour): https://i.imgur.com/SkpY0JP.png

maximize white: https://i.imgur.com/9U0Ziyw.png

EPILEPSY WARNING
then back to normal size white it starts flashing rapidly: https://i.imgur.com/I20l3fQ.gif

in real life it flashes every frame.

@not-fl3 Intel graphics hd 600-620 is known to have some problems with OpenGL 3 btw.

godotengine/godot#25512 for example.

godotengine/godot#64909 another example but on linux.

So Macroquad is probably not the problem here but I'm just wondering why the RED constant works fine and the others don't? This has been the only problem I've seen so far, so it would be "solved" if fixed.

After trying out all constants the ones that work are:

YELLOW, RED, DARKBROWN, BLANK

Some more info, all backgrounds seem to work (except rgb 0, 0, 0) when maximized or after resizing. It seems to only start flashing if the window becomes smaller diagonally. In a maximized completely black window it will still show a small version of the window that's flashing in the bottom left area.
