Hello Mirek,

Alternative diff method doesn't help in this case. For the log in ChGtk3.cpp file:

"Start" = Start
"Before if" = Before if
c = Color(241, 246, 253)
s.itemtext = Color(255, 255, 255)
Diff(c, s.itemtext) = 9
"After if" = After if
c = Color(241, 246, 253)
s.itemtext = Color(0, 0, 0)
Diff(c, s.itemtext) = 246
"End" = End
