Re: Xft, RANDR and subpixel aliasing

Hmmm.

More context: I am running kdrive, compiled for the iPAQ, from familiar
0.7.2 unstable12. It seems to be based on the CVS source from 20031028.
Xft is 4.2.20030122-12, compiled by you :*)

I removed that resource, and it does change things, but only a bit.

Rotating does tell Xft to use different argb values, but only after
restarting the application.

So now all that needs to be done is get Xft to pick up the change
immediately?

Thanks,

Wout.
