[Linux/X11] Image paste does not work after GDClip demo closes

OS: Manjaro
Desktop Environment: KDE, XFCE

Issue: After GDClip demo closes in KDE, clipboard manager fails to store clipboard image from the demo.

The image that gets copied before the demo's execution should be restored after demo finishes its tests (which overwrites clipboard data). The restored image can be pasted while the demo application is running, but fails to work when the demo closes. According to clip_x11 source, Manager hands off clipboard data to a clipboard manager when it is deconstructed.
