Description Christian Fine 2023-12-30 00:56:04 UTC
Description:
I just upgraded from 7.2.x.x to 7.5.9.2. I did not have this problem until I first tried to scroll in 7.5.9.2. Scrolling is disjointed and slow in LibreOffice version 7.5.9.2 when I swipe with two fingers on the trackpad of my MacBook. At first only part of the sheet will scroll. A moment later the rest of the scroll catches up to itself, but not always. The part that is disjointed (does not scroll with the rest of the document) is a vertical strip along the left margin, right through the row numbers of the sheet). I have silmilar issues when I try to scroll by dragging the scroll bar (for both up/down and left/right). However, when I scroll by clicking in the track of the scroll bar, the sheet scrolls as normal and expected. Unfortunately, the scrollbars do not have the arrow buttons that allow for cell-by-cell or line-by-line scrolling.

Steps to Reproduce:
1.Scroll with two fingers on the trackpad (either up/down or left/right, but especially up/down).
2.
3.

Actual Results:
When I scrolled down with two fingers on the track pad, part of the page scrolled and part didn't scroll. Mostly what didn't scroll was a vertical strip of the left margin that cut the row numbers in half. Also there was a rectangle of the sheet (near to the vertical strip) that involved an area about 2 cells wide by 4 cells tall that also did not scroll with the rest of the sheet. 

Expected Results:
The sheet should have scrolled smoothly and instantaneously with my finger swiping.


Reproducible: Always


User Profile Reset: Yes

Additional Info:
There is no "About LibreOffice" option in the dropdown menu under "Help". When I click on the dropdown menu for "LibreOffice" and select "About LibreOffice", a window pops up with information about the version, build, etc. This window has a discrete button that allows me to copy its contents for pasting:

Version: 7.5.9.2 (X86_64) / LibreOffice Community

Sorry for the inconvenience... it's known issue and already resolved in newer versions. There will be no 7.5.10 release..

Quote from bug 158797 comment 2
There is a fix for bug 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

--------
If that does not work, another workaround is to install LibreOffice 7.5.8 or  7.6.3.
