Bug ID: 124968
Summary: UI Performance Sllooowwww on 27" Retina iMac 2019
Model
Product: LibreOffice
Version: 6.2.3.2 release
Hardware: All
OS: Mac OS X (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: UI
Assignee: libreoffice-bugs@lists.freedesktop.org
Reporter: dam...@brightfall.com
Description:
Using either Text Doc, Spreadsheet or Presentation, normal operation is very
slow to the point of being unusable. Simply scrolling the window on a new
document in any app is very laggy. I checked the CPU usage, and it spikes to
50% very quickly. Was trying to create a slide presentation of 20 slides and
some small images (appts 8Mb in total) and the CPU was sitting around 100%. It
seems to be a core UI issue across all Apps I have used.
I have just bought a new 2019 27" iMac, 32GB, 2TB SSD. Clean install with
Mojave. Clean install of LibreOffice 6.2.3.2. Am running it side by side with
my old 27in iMac, which does not show the problem. Seems to be a Retina issue?
Note: I can't select checkbox "Use Hardware Acceleration" it is greyed out and
unchecked.
Steps to Reproduce:
1.Open any doc, eg a spreadsheet
2.Fill in a column worth of numbers, anything really.
3.Scroll up and down or left and right, very laggy.
4.Also watch CPU usage while doing this.
Actual Results:
UI responsiveness is very slow.
Expected Results:
UI responsiveness not be very slow.
Reproducible: Always
User Profile Reset: Yes
OpenGL enabled: Yes
