- Try adjusting the display scaling settings on your system as improper scaling can cause pixelation in GUI windows.
- Increasing screen resolution to higher value may improve the quality of GUI windows.
- Disabling hardware acceleration in Simulink may help resolve the issue. Go to “Preferences” in Simulink -> Simulation then uncheck the “Use hardware acceleration” option.

MATLAB windows' GUI renders just fine and sharp but the Simulink GUI windows have this pixelated aliasing artifacty look

also, the colours are off in some places like the library browser dropdown that appears on clicking on the editor

Hey @Pranav
Here is the possible workaround to fix the pixelated aliasing artifacts in Simulink GUI windows on your Ryzen 9 RTX system:
If none of this works, then consider reaching out to MathWorks support for assistance here: https://in.mathworks.com/support/contact_us.html?s_tid=hp_ff_s_support
Thanks,
