[New-bugs-announce] [issue41595] curses' window.chgat does not change color when specifying curses.A_COLOR

[Maarten]

New submission from Maarten <madebr at gmail.com>:

Or'ing curses.A_COLOR in the `attr` argument of curses.window.chgat ends of with the line not showing.

Actual Problem:
The text is invisible/hidden/not shown.
Using only the attribute curses.A_BLINK is fine.

Expected:
The color of the line is changed +the text starts blinking.


I have attached a small python reproducer and a small c source that shows the correct behavior.
The c example should be compiled as `gcc chgat.c -lncurses -o chgat`.

This is using ncurses 6.1

The c code is from https://tldp.org/HOWTO/NCURSES-Programming-HOWTO/attrib.html,
and the python script is a translation of it.
