            Bug ID: 119163
           Summary: Libreoffice Calc is too slow with some xls documents,
                    containing embedded images
           Product: LibreOffice
           Version: 6.0.3.2 release
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium

Description:
Our company very often work with price-lists from MS Excel, that contain
embedded images, and Libreoffice Calc works with them too slow - CPU usage is
very high and document scroll, cursor moving is very slow too.

MS Excel on same computer works this file very quickly, without hangs.

Seems the source of the problem is in image render module, because if I disable
displaying images in Libreoffice Calc settings, Libreoffice goes to work
quickly.

Example of problem file is here:

Steps to Reproduce:
Open example file, located here:
https://drive.google.com/open?id=1ht9iPrkxHKsN2pK8YiRdm8efdCv1BG4j in

Actual Results:
Libreoffice Calc must works quickly, like MS Office

Expected Results:
Libreoffice Calc works very slow with scrolling document via mouse, also at
moving cursor between cells via keyboard.


Reproducible: Always


User Profile Reset: Yes


OpenGL enabled: Yes
