Improving stations screen glitches

Whenever I press thumbs up or down the screen that comes up and says "improving station" glitches and flickers all over. 

I'm using TG's CM7 on my Motorola Triumph.

Hi. Spotify are unlikely to support custom ROMs as there is too much variation possible. Do you happen to know if it also does this with the standard official ROM for your phone?
