screenshot of Impress showing the problem with slide sorter on a 4k screen

I use LO 7.1.1/kf5 on Linux/KDE using a 4k display with a 200% scaling set.
It seems the slide sorter in Impress does not adapt to this HiDPI setting.
Indeed, the slide previews are small and do not increase when you decrease the number of slides shown on a row below 6.
I attach a screenshot of the problem.

I just found that the same problem exists under Windows, so this is not kf5-specific.
Comment 2 Frederic Parrenin 2021-06-01 09:12:15 UTC
The bug does not exist on the Gtk3 backend, though.
Comment 3 Frederic Parrenin 2021-06-01 09:13:45 UTC
There is a similar bug in the LibreOffice desktop: the thumbnails are too small when using a 200% scaling, so it seems they have a fixed size in pixels.
Comment 4 Frederic Parrenin 2022-01-17 12:50:54 UTC
This problem is still present on 7.2.5, on KDE (Kf5) and on Windows (Win).

What do you expect? On GTK3, when I use "1 silde", the slide sorter does not fill the screen, but with 2 slides or more, it does. In gen UI, the threshold is slightly different. For 1, 2, and 3 slides the screen is not filled, but for 4 slide, it is.
I am using 200% scaling.

I expect to have the same space filled whatever the scaling is.
The scaling should just change the precision of the display, but not the organization of the UI elements.
So for KF5, I expect the screen to be filled with >=2 slides.
