            Bug ID: 70914
          Assignee: libreoffice-bugs@lists.freedesktop.org
           Summary: Terribly low performance of moving tables and text
                    frames
          Severity: critical
    Classification: Unclassified
                OS: Linux (All)
          Reporter: pkola...@gmail.com
          Hardware: x86-64 (AMD64)
            Status: UNCONFIRMED
           Version: 4.1.2.3 release
         Component: Presentation
           Product: LibreOffice

Working with tables and text frames in LibreOffice Impress is nightmare.
Selecting and dragging tables and text frames is extremely laggy, to the point
it is barely usable, which renders the whole Impress Suite barely usable.

A few scenarios where it occurs:
1. Insert an empty 10x2 table. Now try to move it - the UI reacts with delays
of sometimes several seconds (!) and doesn't even display the new position of
the table - so I can't see where I move it. 

2. Now try to select a few cells. Again - there's a considerably huge delay
between clicking and UI reaction. 

3. Insert a text frame. Type 5 words into it. Try to move it. Works flawlessly,
doesn't it? Now type 50 words into it and try the same. Now the lag is clearly
visible. The more text, the more laggy are all the moving / resizing operations
(even basic selection is slow). 

The problem does *not* occur if I select at least *two* objects and move them
together.

Environment information:

OS: Ubuntu 13.04 and 13.10, 64-bit

Hardware: Intel Core i7-2760QM CPU @ 2.40GHz × 8, 24 GB RAM @ 1600 MHz

Libre Office versions: 4.1.2.3, some recent 4.0.x.x and I remember it being a
problem in some late 3.6 version. It feels like it got much worse in 4.1, but I
haven't measured, maybe I'm just tired of it.
