Actually, I noticed minimizing LO and switching back to it resolves the issue. So maybe its a more complex problem where resize/zoom events are not propagated properly.

See the second non-blurry image for comparison.

Dear Kai,
A new major release of LibreOffice is available since this bug was reported.
Could you please try to reproduce it with the latest version of LibreOffice
from https://www.libreoffice.org/download/libreoffice-fresh/ ?
I have set the bug's status to 'NEEDINFO'. Please change it back to
'UNCONFIRMED' if the bug is still present in the latest version.

I do not think this is fixed yet. The behavior seems almost identical too 7.0.1.

Unfortunately I am NOT able to reproduce. Are really all hardware / operating systems affected. A sample impress presentation for reproducing would be nice.
Comment 10 Kai 2022-05-16 17:30:07 UTC
I think this is fixed.

At least on X11 I do not see this issue anymore. I cannot test on Wayland right now, unfortunately.

Closing as "insufficient data" as we don't have a document to test, it hasn't been reproduced, and we don't have hardware / software version info. But please feel free to reopen if you can provide those and still reproduce.
