Armorpaint: GL Errors, crash when changing material properties on Linux

[johhnry]

Hi there,

I am using ArmorPaint v0.7 (2019-11-02) - 0163f27 on a Kali Linux (5.3.0-kali1-amd64 #1 SMP Debian) and when I run the program this is what I get :

# ./Krom ../../build/krom
Uniform N not found.
Uniform texUnpack not found.
Uniform step not found.
Uniform brushScale not found.
Uniform inplast not found.

Then if I edit a material and I change the base color a few times, this is the output :

Uniform brushScale not found.
Uniform brushOpacity not found.
Uniform brushScale not found.
GL Error 1282 ../../Kinc/Backends/Graphics4/OpenGL/Sources/Kore/RenderTargetImpl.c 170
.......
Uniform inplast not found.
Uniform brushOpacity not found.
Uniform brushScale not found.
Uniform inplast not found.
Uniform brushOpacity not found.
GL Error 1281 ../../Kinc/Backends/Graphics4/OpenGL/Sources/Kore/PipelineStateImpl.c 209

[1]    4252 segmentation fault  ./Krom ../../build/krom

Thanks in advance

Hi,

• Which graphics card are you on?
• Are you able to paint normally until you change the material?
• Are you able to paint if you change the base color just once?

Thanks for report!

Hi,

Thanks for your quick reply.
My graphics card is an Intel® HD Graphics 620 (Kaby Lake GT2).

Yes I am able to paint without changing the default material.
In fact I discovered that's it's only when I drag and drop the default material on the cube and then changing the base color of this material (or any other material properties) in the node editor that it crashes.

Here a gif to show the process :
