I am on Win10 Pro. I'm not sure if it is a bug or a missing feature, but when you turn off tab previews in the Settings, they don't actually turn off when you do Ctrl+Tab or Ctrl+PageDown to cycle through them. (I always map tab cycling to Ctrl+Tab and Ctrl+Shift+Tab)

It's rather annoying. I often have a few hundred tabs open. (Many on the exact same website / forums.) If I need to quickly flick through 20 or 30 to check and see if there have been any updates, it slows the process down dramatically. The whole screen flashes, fades dark, a giant scrollable list appears, and the preview is too low quality to read anything. Then you have to fully let go and the screen flashes bright again. It's very jarring. My eyes could focus much easier and it would save me a lot of time if I could just cycle from one tab to the next without the transition effects. When I've got 20 or 30 in a row, traditional tab cycling might only take 10 or 15 seconds to flick through them and take note of whether anything requires reading. With the fade transitions in between, it's more like a minute or two thanks to eye-refocus time.

Thanks. Hope this can be implemented/fixed.
