            Bug ID: 118593
           Summary: Opening first document (odt, ods, odp, docx - NOT txt)
                    pauses for 6-7 seconds
           Product: LibreOffice
           Version: 6.0.3.2 release
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: LibreOffice
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: sasu.liuhanen at gmail.com

Description:
Opening any other document (e.g. odt, ods, odp, docx) than plain text is very
slow, unless one such document is already open in any LO window.
Reader/Calc/Impress window opens instantly, but pauses then for 6-7 seconds
before showing the contents of the document. If the document is opened from
within Writer, it displays "Loading document..." during the wait. The size of
the document doesn't have any perceptible influence on the time.

Purging and reinstalling LO does not help. Neither does removing user profiles
or deleting ~/.config/libreoffice. Using safe-mode changes nothing either.

Having one LO window open and opening any document (other than plain text) in
it, abolishes the whole wait from subsequent opens and everything works as
expected. In summary, LO seems to pause and wait for something while opening
the first document and the wait is gone after the first document is opened.

Steps to Reproduce:
1. Open Reader
2. Open any odt, ods, odp or docx document
3. Program window opens immediately
4. The program waits for something for 6-7 seconds
5. The document opens
6. Open any other document
7. The second document opens immediately

OR

1. Open any above-mentioned document from the command line
2. Program window opens immediately
3. The program waits for something for 6-7 seconds
4. The document opens
5. Open any other document
6. The second document opens immediately

(and the same with Calc and Impress)

Actual Results:
6-7 s wait on opening the first documents, next documents open immediately. 

Expected Results:
More or less immediate document open (at least on empty / almost empty
documents)


Reproducible: Always


User Profile Reset: Yes


OpenGL enabled: Yes

Additional Info:
Enabling / disabling hardware acceleration doesn't change anything. Resources
are not the issue (10 cores, 128GB memory, very fast SSDs).
