A little work-around that sometimes works: Open the Spare Parts app, and un-check "Compatibility Mode". This seems to work fairly well for XiiaLive, DI.fm, and other apps which were shrunk on the screen.
Yes, I've ran into this on a few applications: DI Radio's beta application, iheartradio, Linpack, MorseCoder, Sudoku Free, Solitaire, Lightning Bug, ThrottleCopter, The Weather Channel, Beats (the DDR/Stepmania game), Bash Reader, ManD5, Sipdroid, Tunes Remote, Dotty Original, Calltrack, Wiimote, Bank of America, and ROM manager.

All of the official Google Applications (Goggles, Maps, Gmail, Market, Search, Voice Search, Shopping, etc.) work fine, as do apps such as KeePassDroid, AppBrain, Dropbox, WiFi Analyzer, Runkeeper, Foursquare, ConnectBot, Touiteur, Lookout, Tapatalk/XDA, Sensorly (though their splash screen does not properly show up, and is tiled), Root Explorer, Wardrive, and Dialer One.
