            Bug ID: 389411
           Summary: Okular and X unresponsive when resizing Okular's
                    sidebar
           Product: okular
           Version: 1.3.1
          Platform: Other
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: okular-devel at kde.org
          Reporter: rkflx at lab12.net
  Target Milestone: ---

Open the PDF mentioned in https://phabricator.kde.org/D8379#157345 and change
the width of the sidebar. Moving the mouse to a different window does not
change the cursor anymore, window switching does not work until Okular finished
rendering. Okular's UI is unresponsive too, while normally rendering is done in
a different thread.

Same behaviour when testing in IceWM, so not KWin related.

Additional notes copied from https://phabricator.kde.org/D9328:
I cannot switch windows (or even move window focus via focus-follows-mouse),
which is odd because normally even with all CPU cores busy (here some are idle,
still) that's not a problem. I can move the mouse, but the pointer does not
change. Maybe Okular has a blocking mouse cursor change call, or does too many
of them?

When filing the bug, Bugzilla suggested Bug 155652, so maybe the problem is
related to scrollbars and some Qt code path?
