What graphic card do you use and what Xorg driver. What LibO vlc (generic/gtk2/gtk3/qt4) do you use?
Can you say when this way introduced and can you solve it with some pkg downgrade?

Thanks for your fast reply, your hint regarding LibO vlc pushed me in the right direction. I was able to solve the issue by installing kdelibs (4.14.38-2).

According to the similar Void Linux bug at https://github.com/voidlinux/void-packages/issues/6375

Any interaction with glib2 is probably caused by upstream adding this reversion commit in the latest release: https://github.com/GNOME/glib/commit/4976e8109045b8aa72598668b809418d13e1f031

On my system I'm able to reproduce the bug: when uninstalling kdelibs (4.14.38-2) cpu maxes at 100% with fans running full speed, with kdelibs installed it's all nice and quiet.
Any suggestions on how to further debug this issue? With some help I can try to get a stacktrace on the weekend...

I can also confirm that the downgrade of glib2 from 2.54.3-1 to 2.54.2-2 solves the issue (without kdelibs installed)

Interestingly enough, this happens to me even *with* kdelibs installed (SAL_USE_VCLPLUGIN="gtk3"). Downgrading glib2 to 2.54.2-2 solves it for me.
