Description Armin Le Grand 2024-04-15 11:25:06 UTC

Description:
Rare cases, see description

Steps to Reproduce:
- new Impress, two slides, IASS active
- EditView on slide 2, SlideShow started & at slide 1
- In EditView change slide 2 (e.g. add title)
- in SLideShow next slide

Actual Results:
-> update is missing

Expected Results:
-> update works


Reproducible: Always


User Profile Reset: No

Additional Info:
This happens due to SlideSHow 'Prefetch' of Slide 2, so on changes on 'perfetched' slide also invalidates have to be made in SlideShow (somehow...)
Workaround: once back & forward in SlideSHow
