            Bug ID: 358991
           Summary: X11 Dies From Kodi Fullscreen Switch, Snowballing To
                    pulseaudio, kactivitymanage, ksmserver
           Product: kwin
           Version: 5.5.4
          Platform: Archlinux Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: core
          Assignee: kwin-bugs-n...@kde.org

You can skip to "Issue:".

History: new KDE user, coming from Ubuntu 15.10 and starting with linux via
Ubuntu 15.04. Before that was Vista and ancestral Windows versions.

Reason for change: Vista was practically flawless for me, but I was exploring a
transition to linux.
Ubuntu 15.04 was extremely buggy for me. I'd make bug submissions, but saw very
little results.
Going to 15.10 took care of some issues, but came up with a very notable issue
wherein switching in/out of fullscreen with Chrome or Kodi would (a lot of the
time) result in the GUI freezing (except for the mouse, and screen is left with
that last fullscreen frame), yet audio still played. The only way out was
killing the session or rebooting.

So now I am exploring my options and seem to like the ground-up approach I can
take with Archlinux.
I chose Plasma5, sddm, and tried wayland, but sticking with KDE/X11 for now.
Maybe that is a bad choice for my everyday heavy computer use if Plasma5 is in
beta form.
My logs get flooded with graphical errors ALL OF THE TIME:

Issue: It would seem that fullscreen issue is not just related to Gnome (ubuntu
15.10), since a new way of dealing with it in KDE is with a fullblown X11 crash
(back to the login screen).

Reproducible: Sometimes

Steps to Reproduce:
So far only tested with Kodi (git master (17?))
1) Opened Kodi
2) Watching recorded video
3) Entered fullscreen
4) After some (random) time, exit fullscreen '\'

Actual Results:  
Kicked out of session, back to login screen.

Expected Results:  
Kodi switches back to window-mode.

I'm new with KDE and how bugs should be submitted here, so be gentle if you
would.
I simply pulled the information out of journalctl.

On a different note, I'd like to have a "preview" button before submitting the
bug so I can make sure it looks somewhat decent.
I think github's "Issue" page/form with the markups/preview are something worth
striving towards. (don't know if that is something that I should bother
creating another "wishlist bug" for)
