With intensive generation there is a snow phenomenon on the screen. Can't remove it even if I used the fifo low/high water mark dumped from W95.
With intensive generation in 1024x768 65 Mhz sometimes some points (rubbish, fuzz... hard to explain) appear in memory, like memory violations or memory corruption. It looks like an electronic refresh not well done or VClk too near the MClk. I use the default Mclk set by BIOS. It is hard to reproduce this problem (It can take one hour, two or more). I can't reproduce this problem in 1024x768 75 MHz or 1280x1024 110 MHz or 1152x900 95 MHz.
