Is this bug confirmed? I havn't encountered this on the H320.

I have it as well, but I can't confirm if it's the CPU boost or HD activity.

I get these small random pixels of various colours on the screen.

the problem is now reduced: i only get some small random pixels of various colours on the screen, as said by Jack Chen (chendo)
could you solve even this?!

If anyone is still seeing this problem, please try a new CVS build and see if amiconn's use of DMA to update the H300 LCD has changed anything.
