Qt Wayland blocks in frame callback

    XMLWordPrintable

Details

    • Linux/Wayland
    • 1dc85b95ab0adc1e805d059e2c35c671ef790011 (qt/qtwayland/5.12) 85bb158ddf08aca4d76c13c6a9fcd2637d84d3ea (qt/qtwayland/5.13)

    Description

      When a browser based on qtwebengine is not shown in wayland, it blocks.

      This is most likely caused by waiting on the frame callback, but blocks more than it's supposed to (e.g. copy+paste).

      This also happens when the browser has  more than one window, and only one of them is hidden.

      I was told this works in kwin, but it's observable in rootston/waymonad and probably GNOME.

       

      Tested with qutebrowser and falkon.
