Description amar.bajnath 2020-10-16 20:24:39 UTC
Description:
As i click on a pdf file of a building drawing plan to open, I can see the loading bar at the bottom but it starts hanging about 75% into the load. When it finishes loading (about 5 mins), I cannot do or click on anything because, it starts to hang again and the 'force quit/wait' dialog box comes up.

Steps to Reproduce:
1.Open drawing file
2.Wait for file to load
3.

Actual Results:
Application hangs.

Expected Results:
Should have allowed me to manipulate the file (change the rotation and zoom)


Reproducible: Always


User Profile Reset: Yes


OpenGL enabled: Yes

Very slow to load. I don't see hang in Windows and Linux with LO 7.1+. Just hard to deal with this drawing. And don't know that rotate of page is possible.

I rechecked in 7.3+ Linux and very slow with high CPU so I set New. 
Seems better in Windows, so Linux only so far, also with older.

Comment 14 Roman Kuznetsov 2022-07-02 12:37:52 UTC
LO opens it fast but still takes around 80% CPU load and has some delay while you scroll it in

Version: 7.5.0.0.alpha0+ (x64) / LibreOffice Community
Build ID: e01fc6d7c1353ed2df4d8fcc06bd3b335e89fa04
CPU threads: 4; OS: Windows 10.0 Build 19043; UI render: Skia/Vulkan; VCL: win
Locale: ru-RU (ru_RU); UI: ru-RU
Calc: threaded

But the PDF has over 43 thousands shapes! 

May be better would ask user how open the PDF: as PDF viewer or as PDF editor?

Comment 27 QA Administrators 2025-05-03 03:11:20 UTC
Dear amar.bajnath,

To make sure we're focusing on the bugs that affect our users today, LibreOffice QA is asking bug reporters and confirmers to retest open, confirmed bugs which have not been touched for over a year.

There have been thousands of bug fixes and commits since anyone checked on this bug report. During that time, it's possible that the bug has been fixed, or the details of the problem have changed. We'd really appreciate your help in getting confirmation that the bug is still present.

If you have time, please do the following:

Test to see if the bug is still present with the latest version of LibreOffice from https://www.libreoffice.org/download/

If the bug is present, please leave a comment that includes the information from Help - About LibreOffice.
 
If the bug is NOT present, please set the bug's Status field to RESOLVED-WORKSFORME and leave a comment that includes the information from Help - About LibreOffice.

Please DO NOT

Update the version field
Reply via email (please reply directly on the bug tracker)
Set the bug's Status field to RESOLVED - FIXED (this status has a particular meaning that is not 
appropriate in this case)


If you want to do more to help you can test to see if your issue is a REGRESSION. To do so:
1. Download and install oldest version of LibreOffice (usually 3.3 unless your bug pertains to a feature added after 3.3) from https://downloadarchive.documentfoundation.org/libreoffice/old/

2. Test your bug
3. Leave a comment with your results.
4a. If the bug was present with 3.3 - set version to 'inherited from OOo';
4b. If the bug was not present in 3.3 - add 'regression' to keyword


Feel free to come ask questions or to say hello in our QA chat: https://web.libera.chat/?settings=#libreoffice-qa

Thank you for helping us make LibreOffice even better for everyone!

Warm Regards,
QA Team
