How can I fix a macOS screenshot of an X11 window that’s bleached / white / too light? I'm facing a little problem while taking a screenshot of an X11 window
(using XQuartz - if there's something better out there, lemme know).
I tried everything:

Entire Screen
Window-Only
Selection

Even tried recording the screen, same results - the box I need to screenshot (the one on the right) is always white:

(Side note: In the pic above the window is not &quot;focused&quot; (selected), but even with the &quot;focus&quot; on it, nothing change - even tried using the XQuartz setting where it focus the window on mouseover.)
This is how it should be:

Any idea on what setting I might need to change, in order to get my screenshot to work properly?
Oh... Almost forgot, I'm running the last macOS Catalina update (10.15.6)
Thanks in advance.
I might've found a solution by setting the Output as low as &quot;256 Colors&quot;
This the result

Edit: Added a pic of how it should be.
Edit 2: Added a possible solution.
Go to Preferences under the XQuartz menu and then click on Output. You'll see a pulldown for colors.  Make sure its set to millions of colors. Then restart XQuartz.
