Description Harris.Tiddens 2024-01-11 19:35:19 UTC
Description:
I loaded the new version today
"Version: 7.5.9.2 (X86_64) / LibreOffice Community
Build ID: cdeefe45c17511d326101eed8008ac4092f278a9
CPU threads: 4; OS: Mac OS X 12.7.2; UI render: default; VCL: osx
Locale: nl-NL (nl_NL.UTF-8); UI: nl-NL
Calc: threaded"
And since this new version the scrolling throug a textdocument via sliding the slidebar at the righthand side became very slow.

Actual Results:
Start a larger document. Use the sidebar at the right side to slide

Expected Results:
This is very slow now and acts through small jumps to the wanted position


Reproducible: Always


User Profile Reset: No

Additional Info:
Follow the speed of the sliding as it did in the preceding version

Sorry it is not a text document but a calc document

My first guess is that is the same bug as tdf#155266. There is a fix for tdf#155266 but, unfortunately, the fix will not be available until the LibreOffice 7.6.5 release.

Fortunately, a tester has found a workaround for LibreOffice 7.5.9 and 7.6.4: switch to Skia/Metal rendering.

To enable Skia/Metal rendering, do the following steps:

1. Open the Options dialog by selecting the LibreOffice > Preferences menu
2. Select LibreOffice > View in the left panel
3. In the right panel, check the "Use Skia for all rendering" and uncheck "Force Skia software rendering" checkboxes as shown in the following screen snapshot:

4. Press the "OK" button and restart if prompted

Do the above steps improve scrolling performance?
