Description Telesto 2020-11-05 09:39:03 UTC
Description:
Scrolling document slower showing changes (in a large document also containing comments)

Steps to Reproduce:
1. Open the attached file
2. Wait until page counter finishes
3. Hold page down for 4 seconds -> Page 6
4. Edit -> Track Changes -> Show
5. Scroll up to top first page.. hold page down for 4 seconds


Actual Results:
With show track changes enabled holding page down reaches page 4 (in 4 seconds) with show track changes enabled

Expected Results:
Previously it was page 12.. Of this is correct benchmark.. skipping frames or so.. no clue. but surely smooth.. also when dragging page up/down


Reproducible: Always

Hi Telesto,
Could you please try to reproduce it with a master build from
http://dev-builds.libreoffice.org/daily/master/ ?
You can install it alongside the standard version.
I have set the bug's status to 'NEEDINFO'. Please change it back to
'UNCONFIRMED' if the bug is still present in the master build
