            Bug ID: 128586
           Summary: Each inserted Shape with Gradient Filling blocks UI
                    for a while after Open, Save and Close operations.
           Product: LibreOffice
           Version: 6.1.5.2 release
          Hardware: ARM
                OS: Linux (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Writer
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: j.heras13 at gmail.com

Description:
When opening, closing or saving odt documents, containing Shapes with gradient
infills, gets 100% cpu use for the main thread and blocks the UI for an
unreasonable amount of time.

Steps to Reproduce:
1.Create a new blank Writer document
2.Insert any text
3.Save the file and make note of the time it took to give back UI control. 
4.Insert any Shape using "Menu->Insert->Shape->Basic->Rectangle"
5.Change the propertie "Fill" from "Color" to "Gradient", but do not change any
other properties.
6. Save the file and make note of the time it took to give back UI control. 
7. Make many copies for the new shape and place them any where in the document.
8. Save the file and make note of the time it took to give back UI control. 

Actual Results:
3. The save operation in this step should be instantaneous.
6. It is noticeble an unusual delay. The procesor gets 100% use before
returning the control to the UI.
8. The delay of the operation seems proportional to the number of shapes
created. The time to gat back the control to the UI starts to be ureasonable
long.


Expected Results:
The open, Close and Save operations shoud be reasonable quick and proportional
to the amount of data saved.
Shapes with gradient infill should not affect unreasonably the CPU utilization
of the application.


Reproducible: Always


User Profile Reset: Yes
