Looking at the picture with some magnification it look like

1) we get antialiasing now (which looks really poorly with the used font)

2) the text is antialiased against mask color which then leaks into rendering

Is there a readily available application that shows this?

See AppDB.

I would think that the AA would be visible in other random apps as well but it
might be font dependent.

The AA is clearly visible on the login screen of Fiesta, just type in the name
field.

The colour halo is harder to get. It shows on captions of certain 3D objects.

Programs written in QT4 (especially the UI) also have similar problem, e.g.
Voobly, tsMuxer GUI
UI texts appear lighter / thiner / brighter / less solid than expected. Looks
like something is wrong with with the text gamma or antialising.

Adjusting FontSmoothingGamma value in registry can temporarily make the texts
more solid for now.

Voobly can be downloaed here:

Created attachment 37729
  --> http://bugs.winehq.org/attachment.cgi?id=37729
trace part showing creation and use of a DC rendering distorted font

The trace has around 1G.

At least some of the affected text is rendered using the Verdana font.

I attach log which shows the DC 00004ce4 used for the user name edit box.

The application also creates and loads some fonts files of its own which were
unused in this short trace.

screenshot of said text entry

The antialiasing of this previously clear and readable font makes different
letters appear in different width making text hard to read.

The other issue is that some applications probably rely on the font being
bitmap, not grayscale for their correct operation.

Yes, did not manage to test the patch before 1.3.34 release.

It works flawlessly now.

btw Windows 8 has this issue also when ClearType is enabled.

On the other hand, some other font rendering is awful when ClearType is
disabled.
