Delfina and indivision aga mk2cr

Strange,

very strange problem, but let me try to explain:
i'v got the delfina on my a1200 Motherboard is rev 2b i solved the problem of boot desoldering one cap and not two, i have blizzard 1260, desoldering both capacitors delfinit didn' t find the delfina.library. "on My system"
So i solved the problem of noise changing the place of delfina, i placed the delfina on upper left of the amiga 1200 cover and made a self made cable of 22 pins to reach the clockport.
The problem arise with my indivision aga mk2cr, when i use highgfx screen mode. Infact tryng to play an mp3 or a mod the sound is good but the screen became unstable, he tends to flash intermittently and was divided in two parts. It seems that interlaced mode of highgfx 40.6 as a problem. This with most mod players, amigaamp,amplifier etc. If i use pal interlaced 720x576 all things are good. Any suggestion?
Thx Darkon.

Maybe you need this fixing:

http://aminet.net/package/docs/hard/flickerfix it worked for me with HighGFX. Also clean the pins of Lisa and put a fan if you can. Also I don't think it is related with the delfina. Try running in HighGFX for half an hour without using it and you'll surely have the same problems.

And also you can try this config (the first if HighGFX gives you problems): http://eab.abime.net/showpost.php?p=920520&postcount=97
