Bug ID: 158556
Summary: DOCX Document That Opens/Loads Extremely Slowly
Product: LibreOffice
Version: 7.6.3.2 release
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Writer
Assignee: [email protected]
Reporter: [email protected]
Description:
Attached document does all of these extremely slowly:
- Loading/Opening from scratch
- Jumping to last page
- PAGE UP from last page
Steps to Reproduce:
TEST #1: OPENING DOCUMENT
1) Double-Click on attached DOCX to open it.
Microsoft Word 2016:
- 43 secs
LibreOffice 7.6.3:
- 10 mins 20 secs
While:
- Microsoft Word initially opens it faster
- LibreOffice is staring at a white loading screen
After opening, they both still take quite a while to generate all the pages
too...

LibreOffice 7.6.3:
1) 7 mins 42 secs
