Unreadable button label

I just recently update my MacBook Pro 13" early 2015 to Big Sur, and now on some popups the button's label are unreadable if there is a white or light background (such as in the image 1).

If i place the popup on a dark background, then i can read the button's label (Image 2).

My macOS is in the dark mode, when i use the light mode there is no problem (Image 3 and 4).

Is this a problem with some of my macOS settings that i can fix, is this a bug on the macOS or in the software that aren't updated for Big Sur.

Before the upgrade, there was no issue at all in any mode (dark or light) with any software.
