Re: [Codelite-developers] problem with rendering of "highlight caret line"

[Noel G. <noe...@gm...>]

I think I'm running 2.8.12
I installed it using MacPorts:

Noel-Grandins-MacBook-Pro-15:~ noelgrandin$ sudo port
Warning: port definitions are more than two weeks old, consider using selfupdate
MacPorts 2.0.3
Entering interactive mode... ("help" for help, "quit" to quit)
[Users/noelgrandin] > list wxwidgets
wxWidgets                      @2.8.12         graphics/wxWidgets


I've seen this kind of problem before.
It occurs because the text-rendering layer caches the anti-aliased
character data, which is expensive to generate.
But anti-aliasing has to be done with knowledge of the background
color to work properly.
Which means that the text rendering layer has to be smart enough to
key it's character data cache on both background-color and character
number.
