Simulink colors inconsistent with dark desktop color scheme

I'm using Matlab 2019b on Linux. My desktop color scheme is dark (KDE/Qt), so mostly light text on dark background. Simulink tries to match that for parts of the user interface, which is nice, but it doesn't get it quite right. I get light text on light background and dark text on dark background in some places, which is near unreadable or entirely unreadable (see screenshot, notice the search box, the dropdown menu with search results as well as the navigation bars on top and left of the canvas).

I don't really care too much whether simulink matches my desktop colors or not, but I don't want to change my desktop colors and I would like readable text in Simulink. Simulink appears to have no color scheme settings and is unaffected by color scheme settings in MATLAB.

Have you found a solution?

No.

2022a has the same issue.

Still the same problem for me with matlab 2023b. Have you found a solution ?

Hi.

I'm using environment variables to set a light theme to MATLAB only.

XDG_CURRENT_DESKTOP=GNOME
GTK_THEME=Adwaita:light

And Simulink is light but usable.
