I am experiencing a consistent crash in ArmorPaint related to the Displacement Strength setting and Material Height. The application crashes whenever both values become greater than 0, regardless of the order of operations.

Here are the two scenarios I have confirmed:

Scenario 1:
Set Displacement Strength to a value greater than 0 in Preferences.
Create a new material or select an existing one.
In the Node Editor, attempt to increase the Height value of the Material Output to greater than 0.
Result: ArmorPaint crashes immediately.

Scenario 2:
Create a material and set the Height value of the Material Output to greater than 0.
Go to Preferences.
Attempt to increase the Displacement Strength to a value greater than 0.
Result: ArmorPaint crashes immediately.

Is there any workaround to preview displacement in the viewport without crashing?

Environment:

OS: Windows 11
ArmorPaint Version: v1.0-alpha
Graphics Card: RTX2060super
