I ran into a big NTSC display problem with latest beta.

When NTSC non interlace and OS3.9, a black bar randomly bounces around the screen at about 30 times a second, I'm just guessing on rate.

When NTSC interlace and OS3.9, black bar as before but the whole screen vibrates up and down about one pixel at about 30 times a second, again guessing on the rate and the number of pixels.

I did two screen shots, dumb_001 is the only one that shows anything, the rest are blank as in dumb_002. Paint_001 is a save screen to the clipboard with the GUI showing which freezes everything. You can't see the black bar but you can get an idea as to how much the screen is vibrating up and down.

It doesn't matter whether NTSC or PAL chips set, PAL display works fine, NTSC/PAL both work fine with OS3.1. It appears to be only a problem with NTSC and 3.9. I also checked this with a1200/A4000 quick-start using a standard 3.9. It does this with and without filters. I also sent logs and my config. Previous beta works fine.
