Interface Colors During Error Report

[Fonte Boa]

Edit your preferences.txt and change the line #3 from
{background_color,{0.0,0.0,0.0}}.
to
{background_color,{0.45,0.45,0.45}}.

This will reset background colour to default.

Or do it manually by Edit|Preferences|User Interface, clicking in Desktop/Geometry Background colour and changing RGB slots to any other colour.

-----------

About transparency of windows background colours, you can set it at Edit|Preferences|User Interface, clicking in Dialog Background and set "A" value (Alpha) to 1, to eliminate the transparency. But at the appended preferences.txt there is no settings determining this.

EDIT:
Solved?!
