Description

Hi,

i've found and not usual issue with LxQt and openbox as window manager in VirtualBox environment. First LxQt starts and loads up, then starting qterminal or any other app immediately crashes x11-server-1.20.1.

I've found in Xorg.log.0 this:

Failed to compile FS: 0:11(2): error: colord0 undeclared 0:11(2): error: value of type vec4 cannot be assigned to variable of type error 0:11(2): error: color1` undeclared 0:11(2): error: value of type vec4 cannot be assigned to variable of type error
