Description Sanchke Dellowar 2017-01-29 05:56:56 UTC
Description:
Once I open a file software rendering is forced, and the response of LibreOffice draw is "laggy". HOWEVER when I open a fresh-new blank document (thus avoiding loading a file), it is smooth as butter and no performance decline is noticed.

I use the term software rendering because when I start moving around geometry in Draw on an opened file, a CPU core goes up to 100%. Likewise as stated above, if I open Draw without loading a file and start manipulating geometry, the CPU core only goes up to 30%. This makes it evident that the latter is using hardware rendering to paint the screen.


Steps to Reproduce:
1. Open Draw (do not load file, start with new blank document)
2. Add 6-10 rectangles to the page.
3. Ctrl-A the rectangles and start "shaking them" about the page. Note the CPU usage.
4. Save this document to desktop. Close Draw. Open Draw by double-clicking the document.
5. Preform the same "shaking" to the geometry and notice a slower update rate aswell substantial CPU usage compared to before. 

Actual Results:  
After saved and reopened, libreoffice did not use rendering.

Expected Results:
I expected that sense LibreOffice to use hardware render both before and after the save.


Reproducible: Always

On Linux, when shaking them around I get 60-70% CPU before and after saving & reloading.

Could you please try to reproduce it with the latest version of LibreOffice from https://www.libreoffice.org/download/libreoffice-fresh/ ?
I have set the bug's status to 'NEEDINFO'. Please change it back to 'UNCONFIRMED' if the bug is still present in the latest version.
