Comment 3 Stéphane Guillou (stragu) 2023-08-01 13:27:23 UTC

Reproduced in recent master build:

Version: 24.2.0.0.alpha0+ (X86_64) / LibreOffice Community
Build ID: d16d86685afdf3d321cc282a39a65f38381b6eaa
CPU threads: 8; OS: Linux 5.15; UI render: default; VCL: gtk3
Locale: en-AU (en_AU.UTF-8); UI: en-US
Calc: threaded

With example document, original size is 11.62 × 4.00 cm, second paste in Writer is 11.65 × 4.03 cm, then keeps growing on subsequent pastes.

Before 6.1, size would increase on first paste form 11.61 × 3.99 to 11.61 × 4.01 and eventually plateau at 11.63 × 4.01 after a few pastes, which is still an issue but is barely noticeable by the user.
Similar in OOo 3.3.

Change in behaviour was bibisected with linux-64-6.1 to only a range as paste would crash because of bug 116977: dfefe448c41921f2f1e54d3f69b8b9e89031d055..91b0d2122bdee361bf5412a42d48ff051159cbf2

Notes:
- also reproduce with a simple shape
- not reproduced when pasting into Calc or Draw, and not reproduced when pasting from Writer to Impress. That's because Writer overwrites the select object, whereas other components make copies. I assume it is related to rounding errors and making an object fit into the allocated space when overwriting.
- dimensions can increase or decrease depending on the size of the original object

another sample fontwork

With this fontwork example, the steps result in differently drastic results in 6.0 and 6.1:
- in 6.0, slowly changes dimension and then rapidly reduces in height
- in 6.1, continually increases in height while first increasing, then decreasing, then increasing again in width

So issue depends on original object and did not start in 6.1.
