--- Comment #11 from billstei billstei@hbci.com 2010-06-13 21:11:20 --- Further testing with FL Studio/Harmless, MagicISO ver 5.5, and StreamHijacker:
1) FL Studio itself is also drawing slow, but the Harmless GUI is more noticeable.
2) Comparing FL Studio, Magic ISO, and StreamHijacker, the redraw speeds are very similar. Harmless is much worse.
3) It is not necessary to actually use the GUI on FL Studio, MagicISO, or StreamHijacker, simply put any Linux window in front of them, and then bring-to-front, and watch the repainting. Having the Harmless window open within FL Studio simply makes it more noticeable.
4) FL Studio/Harmless, MagicISO, and StreamHijacker all load gdi32.dll
