Description:
Changing paragraph properties in Libre Office Writer Version: 7.0.0.3 (x64) is very sluggish. If changing the properties of a number of selected paragraphs at the same time it even goes non responding a number of times before settling down, taking a long long time to execute.


Steps to Reproduce:
1.Select a few paragraphs with different settings
2.Bring up the paragraph properties dialog
3.Simply change the indents and observe the slowness of execution or going "not responding" a number of times. Even clicking into an option window to type something in it is taking forever (it seems).

Actual Results:
The properties get changed but after minutes of repetitions of "non response" periods.

Expected Results:
That the properties can be changed in the dialog box within a second or two as in the previous versions.


Reproducible: Always


User Profile Reset: No



Additional Info:
I restarted LibreOffice in safe mode and the bug was not there. I then checked which extension was creating the difficulty and I found out that it was the "Template Changer". Unfortunately I cannot tell you which exact version I had loaded as I removed it now (disabling it did not work and  was just hanging up).
