AGA MKIIcr problems with glitches on screen only on WB ?

[NovaCoder]

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?

Hiya,

It's worth your while to install the latest config tool and make sure you are running the latest core.

That said, it probably won't fix your glitches because the Mrk2 just doesn't seem as stable as the Mrk1.   To be honest 1024x768 is a bit much of AGA anyway, it seems happier when you run it at 800x600 (SuperPlus) or even 640x512 (PAL).    Unfortunately the Mrk2 doesn't really support SuperPlus properly with the latest core so I'm having to run mine at 640x512.

I run my workbench in 1024x768 and the display is always rock solid just like any other mode. I run in 16 colors so the speed is pretty good... with the right palette it looks almost like a GFX card.

Maybe it's just your color depth?   I tried mine in 128 colors and it worked fine for an hour but then started to glitch a little at 1024x768.   I'm now running it 640x512 and 256 colors and it's rock solid (and looks awesome too!)
