I tested extensively in OpenSUSE 42.1 which comes with Plasma 5.3. Most KDE applications freeze for 30 seconds when you start them. It is not only kate or okular. It is dophin and many others.
This happens on my desktop system on which I have a Nvidia Quatro 620 semi professional video card. I have the same system on a laptop with an Intel HD video chip and this problems do not occur. I this thing pissed me off so I did more research and I figured out that if you change the window manager from kwin5 to something else, for example Openbox, the problem goes away, There is obviously a problem Kwin5 has with the Nvidia driver (I have the proprietary one) There is no need to keep this unconfirmed just because you don't have an NVIDIA card and can't reproduce it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1440210 Title: KWin crashes multiple times a day and often has to be restarted manually.
