[Bug] imported PDF shifts to bottom right when switching pages (from v1.7.2)

[xworld21]

Describe the bug

After importing a PDF with multiple pages (such as the one attached), the pages shift by a few pixels towards the bottom right everytime I switch page.

I can reproduce the bug in v1.7.2 and v1.7.3.

To Reproduce

1. Import the attached PDF.
2. Open it.
3. Switch a few times between the pages (PgUp/PgDown, or Left/Right).

Expected behavior

The pages should always appear at the same position.

Actual behavior

The pages slowly shifts to the right and to the bottom.

Screenshots

The page should be at the top left, completely covering the black background.

I think you hit the issue #1009 . It does not only affect pages with imported PDF, but all pages. We investigated into that, but did not find the actual cause and also not a solution for it.

I found the reason and fixed the problem. See #1220. The fix will be part of the next version 1.7.4.
