Description L Duperval 2024-04-03 17:26:27 UTC
Description:
I’m finding that the version is very, very slow. Scrolling is very slow, but the monitors don't show any activity spike on the CPU or the GPU. 

I tried forcing Skia rendering and it doesn’t change anything. I tried using hardware acceleration only and that doesn’t change anything either. In fact, hardware acceleration makes it worse.

Version: 24.2.1.2 (X86_64) / LibreOffice Community
Build ID: db4def46b0453cc22e2d0305797cf981b68ef5ac
CPU threads: 16; OS: Windows 10.0 Build 22631; UI render: default; VCL: win
Locale: en-CA (en_CA); UI: en-US
Calc: CL threaded
Edition 	Windows 11 Home
Version 	23H2
Installed on 	‎2024-‎03-‎13
OS build 	22631.3296
Experience 	Windows Feature Experience Pack 1000.22687.1000.0

Steps to Reproduce:
1. Open a document with a few pages (5-6 at least)
2. Scroll or do anything, pretty much
3.

Actual Results:
It is very sluggish. If I use hardware acceleration I see every icon drawn one after the other and a lot of redrawing.

Expected Results:
Operate smoothly.


Reproducible: Always


User Profile Reset: No

Additional Info:
I downgraded to 7.6.6.1 and that one works correctly.

Have you tested with Skia enable.

Please also check if:
- restarting LO in safe mode helps
- version 24.2.2 is out, might be worth giving it a try
