Window FG/BG colors

Hello,

after installing publickly available GreyEveThemeV2.1 under Windows-10
now some Jitsi dialog windows have lightgrey text on white background
which has a too low contrast for reading/writing. (It very much looks
like Jitsi GUI uses window foreground colors from Windows-10 theme
(light grey, etc) but not the window background colors (white), which
now should be black or very dark grey).

What to do about that? (I have Jitsi 2.10.5550 installed.)
