AGA MKIIcr problems with glitches on screen only on WB ?

[klx300r]

got my A1200 up & running with my Indivision AGA MKIIcr, OS3.9 & noticed after installing the HighGfx monitor modes (1024x768) that I get random screen glitches and artifacts after only 5-10 minutes while in WB but if I run a WHDLoad game or program the screen is fine for many hours with no such issues.
I understand the MKII needed a config program to get it working properly but the cr has worked with no problems since I got it so wondering if the config program is necessary & if it will work for the cr as well?

thanks for the quick responses guys:) found the manual that came with MKIIcr & it does mention pixel flickering might occur while using HighGFX driver due to heat issues so I think I'll reinstall my fan & add a heat sink to Alice tomorrow. I'll also install the latest tool from Jens. Timing fix seems easy enough if problem persists else just go back to 800x600 as that's what i was running before with no issues.

btw, I got rid of my 2'nd CF IDE as my DH0 as they just seem to get corrupted too easily over time and now got my 'real' 2.5" IDE drive in my A1200 which of course gets really hot after a while so getting rid of heat is always a good thing.  Btw, my Subway USB gets darn hot too come to think of it.

update: installed a low profile heat sink on Lisa and fan inside the case first thing this morning and my 1200 has been running for 8 hours now with no problems at 1024x768 so problem appears to be solved :-)
I think I'll be using 800x600 as WB is alot more snappy with it on my system though 1024x768 is much faster if I go down to 16 colours. Also haven't tried Jen's tune program yet as all screens seem to be working fine without it so far.

looks like a nice cool setup there:) I only have one small fan on the underside of the top cover but hey the more cooling the better if you don't mind the exrta hum that is

@ magnetic

my 1d4 is a Commodore one & PAL version. As for the config tool, I have no idea as mine is ok right out of the box for what i need and understand people have had issues with it. Anyhow if you try it let us know how it goes
