Impress slideshow problem and performance issue

I have setup a new laptop(Fresh install) and I want to transfer everything to my new laptop, but there are problems keeping me from switching to my new laptop:

  1. I have tried to install different version of liberoffice, from laptop version) to 6.15, but no luck on performance, I even tried the solution from others, uninstall and reinstall using x86 or x64. 6.2.2 beta doesn’t have this problem.

  2. Starting from, my slide having problem with alignment, as picture below

Old PC:
Chuwi hi12
Intel Atom X5-Z8300

New PC:
Chuwi hi13
Intel Apollo Lake Celeron N3450

Thank you very much.

I can’t tell what’s going on in your picture. A better depiction of the problem might allow someone to help you.

The yellow box increased height in the newer version, sorry about the confusion
