Description Telesto 2016-10-15 17:47:59 UTC
If my Macbook Air (tested with: Yosemite, El Capitan, MacOS Sierra) goes to sleep and i have plenty of writer documents opened (for example 14) with LO version (or higher) (with a stored (stock) User Profile), on resume LibreOffice Writer will function normally until the point where I create a New Document. CPU will go up to 100% for one or more minutes depending on the number of opened documents and the used LO version; with the LO 5 a little bit worse than the LO 4.4 series. When the CPU spike ends everything is back to normal; opening a new documents will take a few seconds. The proces will repeat itself after every Mac nap.

The problem doesn't occur if:
- the affect LO version is used in the first run (no saved profile)
- in Yosemite, El Capitan, MacOS Sierra with Libreoffice (and lower versions: not tested)
- in Mavericks

The affected system is a MacBook Air 11" Early 2014.

Steps to Reproduce:
1. Use a Mac with MacOS Yosemite, El Capitan, MacOS Sierr;  No user profile
2. Start LibreOffice Writer for the first time (to generate a user profile)
3. Close Libreoffice (CMD+Q)
4. Start Libreoffice Writer again
5. Create plenty blank documents (14 or more)
6. Put your computer to sleep (Choose Sleep from the Apple menu; Click Sleep after pressing the power key; Close the lid of a portable Mac)
7. Wait 10 seconds or more (just in case)
8. Wake Mac again
7. Enter password (security setting)
9. Create a new document (CMD + N) or click new document in the menu bar
10. A new document will show up, but isn't responding. CPU usage spikes to 100%.

Actual Results:  
LibreOffice is unresponsive and CPU usage is around 100% for one or more minutes depending on the number of opened documents.

Expected Results:
LibreOffice is responsive

Reproducible: Always

User Profile Reset: YES
