I'm currently running Simulink on a Ryzen 9 RTX 3060 laptop through (K)Ubuntu 22.04 LTS (running natively) with the proprietary drivers:

>> opengl info

Version: '4.6 (Compatibility Profile) Mesa 22.2.5-0ubuntu0.1~22.04.3'

Vendor: 'AMD'

Renderer: 'RENOIR (renoir, LLVM 15.0.7, DRM 3.49, 6.2.0-26-generic)'

MaxTextureSize: 16384

Visual: 'Visual 0x67a, (RGBA 32 bits (8 8 8 8), Z depth 16 bits, Hardware acceleration, Double buffer, Antialias 8 samples)'

Software: 'false'

HardwareSupportLevel: 'full'

SupportsGraphicsSmoothing: 1

SupportsDepthPeelTransparency: 1

SupportsAlignVertexCenters: 1

Extensions: {312×1 cell}

MaxFrameBufferSize: 16384

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

please help me out with this, thanks!

Hey @Pranav

Here is the possible workaround to fix the pixelated aliasing artifacts in Simulink GUI windows on your Ryzen 9 RTX system:

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.

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,

Reverting display scaling to 100% seemed to have fixed the pixelation issue! The colouration issue still persists but is far less an issue than the latter. Thanks a lot!
