Super OLED - how's eye tracking?

I finally received OLED optical module as a replacement for my UW with mura.

I couldn't get eye tracking calibration to work whatever I tried, and eye tracking was all over the place, totally unusable (in DCS) - blinking,flickering, resolution changing back and forth, frame jumping all over the place... Support recommended yesterdays (!) update to 1.47.9 which made the calibration work and improved eyetracking somewhat, but it is still pretty bad compared to UW. It can go to low res (non-gaze area) randomly while i'm looking straight forward without moving my head or eyes, and the gaze area frame is visibly shakind at times. With UW nothing like that ever happened.

I know OLED is still work in progress and i hope it is just software, but not sure if it is that or if i just got a dodgy module again. How's everyone else who's got OLED doing with eye tracking?

PS. I love the picture of OLED, no mura at all and clarity is phenomenal (and colors of course). But the FOV it not so good. And it is not even FOV (it feels 'boxed' compared to UW but i could live with that) but the distortion, with UW i can keep my head locked and use my eyes to observe pretty much the entire visible area, with a little distortion only at the very edge. With OLED i can probaly turn my eyes like 30 degress horizontally (a bit more vertically) before the picture goes bad (colours go weird, distortion, one eye almost stops seeing it). Technically i get around 108 horizontal FOV (vs 124 UW) but realistically it is more limited and i'd have to turn my head a lot more. Probaly just the matter of habit but doesn't feel good. I'm really puzzled now, either sick with mura-infested UW that has crappy picture quality on bright colours, or with OLED that has amazing picture as long as you're looking mostly straight forward and not using eye tracking. Damn, i wish the UW just wasn't so bad with mura.
