Not skia specific
Comment 2 Xisco Faulí 2021-02-15 18:06:16 UTC
Hello Telesto,
I believe this issue might be fixed now after
https://git.libreoffice.org/core/commit/27a4aea50a9efa5c839b0ae2de1f9f14a7782f11.
Could you please try to reproduce it with a master build from
http://dev-builds.libreoffice.org/daily/master/ ?
You can install it alongside the standard version.
I have set the bug's status to 'NEEDINFO'. Please change it back to
'UNCONFIRMED' if the bug is still present in the master build

Issue still reproducible in 7.3.4.2. Scrolling with ctrl still produces half a second of lag before zooming in.
