            Bug ID: 98854
           Summary: segfault with javafx fullscreen + yakuake when
                    compositing disabled
           Product: xorg
           Version: git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/AMDgpu
          Assignee: xorg-driver-ati at lists.x.org
          Reporter: haagch at frickel.club
        QA Contact: xorg-team at lists.x.org

Found this while testing this program
Happens on X.org 1.18 and 1.19.

Steps to reproduce:
Disable compositing
start java Jfxtest
quickly press the hotkey for opening yakuake, possibly several times
X.org will likely crash.

With debug symbols I caught this assert:
