Hi Fernando,

thanks for the informations! :)

I am not using compiz or such....

Openbox is installed as follows:

[I] x11-wm/openbox
     Available versions:  (3) 3.5.2-r1 (~)3.6 3.6.1 **9999
       {branding debug imlib nls session startup-notification static-libs svg xdg PYTHON_TARGETS="python2_7"}
     Installed versions:  3.6.1(3)(11:01:40 AM 02/18/2017)(nls session -branding -debug -imlib -startup-notification -static-libs -svg -xdg PYTHON_TARGETS="python2_7")
     Homepage:            http://openbox.org/
     Description:         A standards compliant, fast, light-weight, extensible window manager

My USE_FLAGS (make.conf) are:
USE="nvidia X lua sdl mp3 flac jack alsa gtk cairo sndfile qt3support kpathsea gif tga jpeg png jpeg2k mad dvb dvdr encode lzo bzip2 ogg sox v4l v4l2 vorbis x264 x265 zsh-completion -hal -lirc"

Wpuld you suggest to change a flag?

Thanks a lot for any help in advance!
