Description Stephan Diestelhorst 2016-02-26 13:44:09 UTC
After a while of using kmail (5.0.2 KDE Frameworks: 5.15.0, Qt 5.4.2), it seems that the message preview below the message list stops scrolling properly.  I can still scroll, but if I scroll down, only the lower ~50 pixels (~2 lines of text) get updated.  When I scroll up, it is only the top 50 pixels in that window.  The rest stays exactly flat.

I have tried disabling Desktop Effects (Alt + Shift + F12), but that does not resolve the problem once it has occurred.  I also played with the KDE compositor settings and selected all different tearing options, GL versions etc, but nothing helped.

The only way to fix this seems to be to restart KMail for now.  Then it continues working for a while, I have not yet identified when this happens.  I usually can work for (felt) 30 mins to several hours until this turns up again.

This happens for both HTML and text emails.  Going to the next message will render the full view correctly.  Resizing the preview pane does not have an effect, other than temporarily rendering the screen correctly.

Reproducible: Always

Steps to Reproduce:
1. browse emails and use the preview window and scroll
2. do this for a while
3. observe the scrolling not affecting the middle of the window

Actual Results:  
the middle of the rendered email does not move on the screen

Expected Results:  
the entire message scrolls up and down

kubuntu package: 4:15.08.2-0ubuntu1
