The glitches I had was solved by reducing the pixel clock, not the GPU clock.
Go to MorphOS preferences / Monitors panel. Pixel clock has a slider : lowering the pixel clock helped a lot to solve the graphical glitches. Be gentle with the slider : the monitor can go out of sync !
My display even blacked out after some seconds of heavy screen corruption. This problem only showed with 1680x1050 screens also.
Be sure that the mini is dust free inside : heat can trigger the problem as well. Open the case, clean the fan & heatsink with some dry air spray. It will increase the life length of the mini too. I know someone who had to buy a brand new mac mini fan from US. Costed near 80€ (fan + shipping + VAT + import taxes)... Pretty expensive !
