HiDPI or dual-screen regression with Opera-beta 32.0.1948.12

  • There is a regression in the just released Opera-beta 32.0.1948.12.

    When I right click a tab within about 200 pixels from my right edge - of my left screen, the pop-up appear on the wrong monitor.
    Same with mouse over.
    DPI here is at 107.

    The single ever Opera-beta version that just works is: 32.0.1948.4

    Note: Dual screen and HiDPI never worked well for me in Chrome/Chromium - any version (including latest unstable) of these exhibit similar or worse behaviour unless DPI scaling is disabled.

  • ..In addition to previous post, following conditions are needed to trigger the issue:
    Opera need to be positioned near the right edge of a monitor with high resolution (4K or QHD) with a low resolution secondary display (ordinary HD).
    I tested two different systems, 4K and QHD: 3840 pixels wide and 2560 pixels wide both trigger it in a dual screen setup with a normal "HD/1920" secondary.
