OpenShot 2.1 freezes upon startup (suspected focus issue) on LM 17.3 Xfce (Ubuntu 14.04 base)

[Hachmann]

I just upgraded to the latest openshot version which I installed from the ppa (http://ppa.launchpad.net/openshot.developers/ppa/ubuntu/ trusty/main amd64 Packages)

What I got when I tried it out seems to be a focus problem with the tutorials bubble.

After starting the application, the 'bubble' with the tutorial flickered continuously, and did not react to clicks on its buttons.

CPU load skyrocketed.

While I drag the openshot window, the CPU load goes down, and the flickering stops.

Alt+Tab to switch applications did not work anymore, because the tutorial thing appears to steal the focus.

I was able to load a gif file, though, once. After this, openshot did not react to any further clicks I made in its interface.

Closing the application via the window decoration buttons works, fortunately.

Is there a workaround to deactivate the tutorials, via some preference setting, maybe? Could be that would be all that's needed for openshot to at least be usable.

Tested again with Linux Mint 18 (Xenial base) and OpenShot 2.2. AppImage doesn't work at all, because of this bug.

Still experiencing the flickering tutorial bubble in 2.3.0 on Linux Mint 18.1 (from http://ppa.launchpad.net/openshot.developers/ppa/ubuntu xenial/main) - the application is unusable for me, because I cannot get past the tutorial bubble.

Running Openshot 2.3.4 on xubuntu 16.04 and the tutorial
window really annoys. Clicking on main openshot the
tutorial popup goes away but moving mouse off openshot
and back on it the popup comes back.

Using xfce..

As reported above, the buttons on the popup cannot be clicked,
attempting to click in the popup accomplishes nothing.

Adding a photo of the popup on openshot
