Hello Rafael,

shure I can. The BUG comes up in every document I work with but if the doc have only one side I haven't to scroll so the Problem don't come up.

The Doc I provide here is a 9 page rental contract...

Thanks for the test file.

I opened it in LO 7.4 beta and scrolling was fine using the scrollbar, the mouse scroll-wheel, as well as PgUp and PgDown keys.

Tested with

Version: / LibreOffice Community
Build ID: 78335f5ba9bae4f1b429bebd56ff5991192e8650
CPU threads: 16; OS: Linux 5.13; UI render: default; VCL: kf5 (cairo+xcb)
Locale: pt-BR (pt_BR.UTF-8); UI: en-US
Calc: threaded

I also tested with LO 7.3.4, LO 7.2.7 and LO 7.5 alpha and all of them worked fine.

Let's see if anyone else can reproduce this bug.

A guess:
Tools -> Options -> View -> Check Force Skia Software Rendering. Press OK and restart LibreOffice. Does the crash still happen after the change?
Comment 6 Michael Buchholz 2022-07-07 20:57:03 UTC
Hello Rafael,

I just checked "force Skia" but noticed that "Skia is currently enabled" is already showing.
I've now tried it with the forced Skia again and right now I couldn't reproduce the error on a quick test.
I'll see it again tomorrow in active work on the document (it's still a draft); I have to go to bed now ;o)

At this point, many thanks for your support. I'll report tomorrow if that helped.
If it helps, Skia seems to say goodbye while working and the display that Skia is active is not necessarily true or only sometimes... I think...

Good night at this point...

(sorry for my ugly english...)

I guess we may mark duplicate, to concentrate this. 
In these bugs, where testers cannnot reproduce and they obviously depend on a system, we must rely on reporters to test daily master. 
Please do install from https://dev-builds.libreoffice.org/daily/master/current.html it's separate to working LO and will not take over your extensions.
Please test No Skia, Skia Raster (no graph card support), Skia Vulkan (graphic car support).
