Also happening in 7.0 branch?

Not the same behavior, so not the same bug.

It only affects scrolling, not typing.

Still believe to be same core issue, showing different symptoms... Please add an example file with some images showing the problem.. as image can have different formats, sizes etc..

Thank you for reporting the bug. Please attach a sample document, as this makes it easier for us to verify the bug. 
I have set the bug's status to 'NEEDINFO'. Please change it back to 'UNCONFIRMED' once the requested document is provided.

Would still say: bug 138125 / bug 138068 (both duplicates of each other)

Repro with GDI not with Skia

Hello Alberto Salvia,
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

Tested with:
https://dev-builds.libreoffice.org/daily/master/Linux-rpm_deb-x86_64@86-TDF-dbg/current/

The result was the same as in the screen-cast on fist comment, so not fixed.

Just for the record, you are using a debug build ( -dbg in the name ) which might run slower. Could you please try with https://dev-builds.libreoffice.org/daily/master/Linux-rpm_deb-x86_64@86-TDF/2021-02-15_20.07.52/master~2021-02-15_20.07.52_LibreOfficeDev_7.2.0.0.alpha0_Linux_x86-64_deb.tar.gz ?

I'm on Manjaro Linux.

None of those packages seem to work, even when manually extracted and copied to the filesystem:

error while loading shared libraries: libuno_sal.so.3: cannot open shared object file: No such file or directory

Perhaps for Linux development snapshots having appimages only would be a better idea:
https://bugs.documentfoundation.org/show_bug.cgi?id=140548

Shall I try to compile this myself, or will it be too time draining?

Assuming it's solved, marking this as duplicate again.
