Hey folks,

When playing something in vlc and moving my mouse pointer over the time slider, the desktop freezes until the media ends.
No key input is accepted until the end of the freeze.

I can reproduce it on a freshly installed Fedora on a VM.

Reproducer:
- install fedora 26
- # dnf upgrade
- # dnf install https://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm
- # dnf install vlc
- Set VLC as default for Music and Video in 'All Settings'->'Details'->'Deault Applications'
- Download 2 audio files
- Close all windows & open nautilus & browse to folder containing audio
- Open 1 audio file, move vlc player to side next to nautils
- Bring nautilus to foreground
- open another audio file
- move mouse pointer over time slider
* freeze happens *
