    Details

    • Type: Bug
    • Status: Reported
    • Priority: P1: Critical
    • Resolution: Unresolved
    • Affects Version/s: 5.12.1, 6.2.2, 6.3.0

    • Component/s: WebEngine

      Description

      To reproduce:

      • Start bar>Search for 'language settings', and ensure there are two available languages
      • Start bar>Search for 'advanced keyboard settings'
      • In subsequent window, click on 'language bar options', then the 'advanced key settings' tab
      • Set up hot keys to switch between the two languages, such as shift+alt+1 and shift+alt+2
      • Run the webengine markdown sample app on a system that supports hardware acceleration (tested on a system with an Nvidia card, and one with Intel graphics)
      • Press the shortcut key for the input method that's not currently enabled, and observe the app has hung.

      Notes:

      • On systems which don't support hardware acceleration, or when QT_OPENGL is set to software, the issue can't be reproduced.
      • A user reported an earlier build with Qt 5.9 doesn't exhibit the issue. Another user's report seems to indicate the issue exists with Qt 5.9 as well.
