Plasma/5.9 Errata

Known issues in the Plasma 5.9 release.

Freezes Using Qt 5.6.0

• http://bugreports.qt.io/browse/QTBUG-51676
• https://bugs.kde.org/show_bug.cgi?id=359611

When using Qt 5.6.0 Plasma loads itself incompletely and with long delays. Deadlocks occur in kded5. Use Qt 5.6.1 or Qt 5.7.1 instead.

Plasma Discover With Qt 5.7.1

Discover 375083 crashes with Qt 5.7, use Qt 5.7.1 instead.

Intel GPUs

We recommend the Xorg modesetting DDX for use with Intel hardware. This is the default in many distributions nowadays. Using the Intel Xorg DDX can result in various graphical glitches and freezes.
