Description Murz 2018-08-09 06:47:52 UTC
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: https://drive.google.com/open?id=1ht9iPrkxHKsN2pK8YiRdm8efdCv1BG4j

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

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

Slow is not file opening time, but Libreoffice Calc interface when working with document - scroll via mouse, select cells, move between cells via mouse, etc.

Wow there are 9000 images in the file. Changing to ods file type doesn't help.
There are work in progress about images manage.
Hi @Armin, maybe are you interested on take a look to sample file.
