# Malt Gotchas

This page will document known quirks you have to pay attention to when working with Malt along with other software.

### Malt window

![](/files/-MbdhrIpwwBIR4LFmk6h)

This tiny window is Malt's window aka the renderer. This window exist because Malt is a separate process from Blender. Never close this window when working with BEER/Malt.

{% hint style="success" %}
Always keep the Malt window running in the background.
{% endhint %}

### Malt crashes with MSI AfterBurner OSD (on screen display)

![](/files/-Mbdkbcs_otuVXycwgVV)

It comes to our attention that the resource and performance monitor, MSI Afterburner's OSD will crash Malt on launch. Malt window appears for a split second and then vanish.

Known version to crash Malt: MSI AfterBurner v4.6.3

{% hint style="success" %}
**Remedy**: If you still want to use MSI Afterburner, make sure to turn off OSD before starting BEER/Malt
{% endhint %}

### My mesh is yellow

![Yellow mesh means the material is empty. To solve this, add a material and load a shader.](/files/-McWUXrUkjMHUsxgm_eJ)

### My Mesh is grey

![Using the basic.mesh.glsl shader and a point light.](/files/-McWVC4mRa8XnZLtarCu)

The cause of this problem is the default radius of the point lamp. By default the radius is only 5 unit. The light cannot reach the cube.

![Point light radius too small to reach the object in the origin](/files/-McWVlmx8FRuthGLKwr1)

{% hint style="success" %}
Solution: Increase the *point light* **radius** or change the light type to *sun.*
{% endhint %}

### Malt running super slow

If you have a 4k monitor/screen, Malt might run super slow and laggy. The reason for the major slowdown is most likely because your machine just can't handle rendering realtime shaders in 4k resolution.

{% hint style="success" %}
Solution: lower the display resolution to **2k** or **full HD** to get smooth and responsive viewport performance
{% endhint %}

### Blender from Microsoft Store

![](/files/-Mdh2lHk-GM3tJVWY6tI)

Malt doesn't work when Blender is installed from the Microsoft Store. This happens because Windows pervent user from tempering the WindowsApps folder.

{% hint style="success" %}
Solution: Please download Blender installer or the archive (.zip) from Blender.org
{% endhint %}
