Description Piotr Osada 2022-11-29 14:40:56 UTC 
Description:
As it is shown in attached movie writer is hanging/suspending when we scroll to a table in attached document.

Original document have 12 MB and contains more than 50 images. Attached one is an template of original witch the same arrangement of sections, captions, and tables. The table contains example data the in the same order as in original document.

Steps to Reproduce:
In original document:
1) Open document,
2) scroll down to the table,
3) Writer hangs (I don't know for how long).

In compilation (attached template)
1) Open document,
2) do something (click on cells, select ranges, drag and drop content, and ESPECIALLY: COPY AND PASTE some ranges),
3) Writer hangs (for 30 seconds or even for 2 minutes). 

Actual Results:
On Windows Writer responds after about 30-120 s.
On Linux it seems to last longer (I didn't get an answer. At least after one minute). 

Expected Results:
As in MS Word, Writer should respond within milliseconds (less than one second at worst).


Reproducible: Always


User Profile Reset: No

Template of 12 MB original document that causes even more intensive hangs.

The video shows program hang when editing the table. In the original document, the program crashed after scrolling to the table.

Done this with the attached document:
Opened the document, scrolled down, clicked in the table, scrolled up. Scrolling up hangs.
Save the document as *.odt
Closed document, opened it again and down the same as described above. Couldn't detect any buggy behavior with document in *.odt-format.
