Simulink white font on white background

Part of simulink window displays white fonts on white background. I dug through all the application and system settings I could find, but no changes affect this window. Is this possible to change this font to black?

System: Archlinux

Matlab version: R2022b

The only log I get when app starts is:

MATLAB is selecting SOFTWARE OPENGL rendering. Fontconfig warning: "/usr/share/fontconfig/conf.avail/05-reset-dirs-sample.conf", line 6: unknown element "reset-dirs"

Hello,

same situation here:

Matlab 2022b Update 2 installed on opensuse 15.4 x64 with KDE and the Dark Breeze theme from KDE.

@Tomasz Kisiel There is a temporary workaround to switch to normal Breeze theme from KDE. The result is black font on white background

@MathWorks Support Team There is a very annoying bug in Simulink 2022b update 2 for Linux especially for KDE when using a dark theme. The workaround is as it says woking, but my eyes go mad.

Okay, even a better workaround:

1. Switch KDE Theme to normal
2. Start MATLAB
3. Start Simulink
4. Switch KDE Theme to dark
5. Invert MATLAB and Simulink if necessary with KDE Plugin

Resulst: KDE Theme is dark, all symbols are readable, or if desired inverted (white font on black background)
