Broken font rendering on virtual desktop

Hi all,
We use virtual desktops here and with 17.1 the font rendering got really crappy in Chrome and Firefox. Internet Explorer is still good. In Chrome it "helps" to disable remote fonts using "/disable-remote-fonts". The problem is that all the small Appian specific icons do not show up anymore.

In the virtualized Windows 7, font smoothing "clearType" seems to be disabled. Not sure if this makes a difference as IE is good and Chrome with disabled remote fonts is good.

Any ideas?
