Three finger swipe (and HiDPI setting)

  • At least on my computer (Samsung Book9) Opera 20 (using 20.0.1387.64) does not support laptop trackpad three finger swipe back and forward. I have enabled it in Control Panel / Touchpad / Three-Finger Swipe. And it works nicely in Firefox, Chrome and Internet Explorer. But Opera seems to intercept that somehow. Only the Opera-specific moveMouseLeft+RightMouse works (that's Back), but that's totally useless on a trackpad. Why does three finger swipe not work and how to get it working?

    I have also another question: My computer has a very high resolution screen. So by default, Opera (and Chrome, but not Firefox or IE) has a very tiny UI at the top. Way too small to see anything. I could get that fixed by doing opera://flags and there Enable HiDPI Support. But after a certain update (or atleast possibly that had an effect, more specifically a Samsung driver update), the Enable HiDPI function broke. There is only way too big UI now, and it's off target, everything is out of place and not working properly. So instead of the HiDPI function I think we need a zoomable UI size, or at least say default, bigger, very big or something like that.

  • I can confirm that 3-finger-issue (I wasn't aware of it since I don't use another browser, but just tested it in Chrome)

  • I have the same problem with the three-finger-swipe on my "samsung ativ book 9"(Elan Touchpad).
    Back/Forward works everywhere except in Opera.
    Anybody found a solution? (I tried Opera-Next and the problem is still there)
