            Bug ID: 354082
           Summary: high cpu usage for screen redrawing with qt5.5
           Product: konsole
           Version: 15.08.0
          Platform: Gentoo Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: konsole-devel at kde.org
          Reporter: kvaster at gmail.com

konsole eats cpu redraw compiled with qt5.5. There are no problems with qt4.4
or konsole-4.14.3.

Reproducible: Always

Steps to Reproduce:
1. Launch any program with lot's of output (fill konsole's output buffer)
2. Try to select text with mouse - move mouse pointer constantly.

Actual Results:  
100% cpu usage

Expected Results:  
low cpu usage

Selecting text with mouse it not root cause of the problem. High cpu usage can
be noticed during any text output (redrawing).
