Since I’ve abandoned OpenBSD for FreeBSD in my recent attempts to actually use a ‘real’ UNIX system, and all that just because of Wine so I can use some small Windows tools I need (yeah…), I was a bit fed up with Wines’ font anti-aliasing not working. I remember having a similar problem on CentOS Linux some while back, but I can’t remember how I solved it on that OS. Thing is, I just want to document my solution here briefly, so I don’t forget it, if I have to re-do this any time soon. The problem seems to originate from the X11 render extension that is being used for compositing on X11 without any additional compositing engine like Compiz. Wines usage of the extension is actually controlled by its system registry, and the key that seems to need editing is HKEY_CURRENT_USER\Software\Wine\X11 Driver\ClientSideWithRender.
Interestingly, people suggested to switch the use of the X render extension off instead of on, but when inspecting my setup by running wine regedit, I found I didn’t even have the key, and its default is off! So what saved me was:
Setting this back to “N” is basically the same thing as just deleting the key altogether, at least with the current default configuration of my Wine version on FreeBSD, which is wine-1.6.2. See how it looks like with no anti-aliasing (click to enlarge):
And here with proper AA, again, please click to enlarge so you can see the effect applied:
To demonstrate the effect more prominently, let’s look at some zoomed in versions, click to enlarge again for all the glory or so:
Now I heard that some people actually prefer the clearer look of jagged fonts, or they may prefer pure gray smoothing, but I actually like the look of this smoothing a lot more. This is with medium font hinting turned on in Xfce4, and it appears very smooth and nice to my eyes.
If you want to try this in case you’re offended by jagged fonts using wine, just take the following:
Save it into a file like wine-Xrender-fontAA.reg, and then import it into your wines registry database by opening a terminal, going into the directory where your reg file sits, and by running: wine regedit ./wine-Xrender-fontAA.reg. Then restart your wine application and it should work for 99% of the fonts. I’ve encountered one font in Bruce Schneiers [PasswordSafe] that wouldn’t anti-alias, ever. But it’s the same on Windows, so I’m guessing that’s ok.
Switching it off is just as easy, just edit the file, change “Y” to “N” and re-run the wine regedit command. But as I said, I’ll keep it, no more eye cancer when starting Win32 applications on FreeBSD.
