            Bug ID: 142244
           Summary: CPU 1/3 busy without user action and console flooded
                    with
                    warn:legacy.osl:20384:20384:vcl/source/outdev/bitmap.c
                    xx:463: CopyBits with zero or negative width or height
           Product: LibreOffice
           Version: 7.2.0.0.alpha0+ Master
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Impress
          Assignee: libreoffice-bugs at lists.freedesktop.org

Bug document

Simply opening the attached presentation without any action in the GUI
or otherwise, just letting LibreOffice sit idle, spams the console with
~1500 instances of

   warn:legacy.osl:20384:20384:vcl/source/outdev/bitmap.cxx:463: 
   CopyBits with zero or negative width or height

per *minute*.

How to reproduce:

   1. Save attachment as circle.pptx
   2. Open a (Unix-type) shell
   3. date ; lo circle.pptx 2>&1 | grep CopyBits | wc -l ; date

In a test I did on my notebook, this gave me

   ... 21:06:16 CEST
   514
   ... 21:06:37 CEST


There's two issues here: the spamming of the console, but maybe more
importantly - what is LibreOffice doing in a tight loop apparently when
there is no user action at all?
