--- Comment #3 from Buovjaga <ilmari.lauhakangas at libreoffice.org> ---
The AskLibO link is a red herring. This started happening with version 7.1.
Bibisected with linux-64-7.1 to
https://git.libreoffice.org/core/commit/bf021c369f2306ee507da9bd3cc4cd10ac5d234c
tdf#135500: always use transparent and clear content vdev in impBufferDevice

As mentioned in the summary, the lag can be seen simply by switching the slides
in the slide pane with PgUp/PgDn. However, you have to have the window
maximised to really notice it.

I don't observe the lag on Windows.
