Wasn't sure which view to file this under, since they're all involved somehow. After using compact view, switching to details view will show only a blank area where files should be. This remains blank when switching to icons view, but you can switch back to compact view. Resizing the window doesn't change this. Pressing F5 does no good. Behavior remains until dolphin is restarted. Reproducible: Always Dolphin version 17.12.3 on Arch x86_64. Reproduced with both Oxygen and Breeze widget styles. Window width does seem to make a difference. For me, it works when the white space of the files area is 353 or 360 pixels wide (I'm sure many other sizes too - didn't check; but it didn't work when full screen or when the files area was about 50% larger.) (Probably not relevant, but I use "Use common properties for all folders" under General : View preferences.) Steps to reproduce: 0) Set dolphin to a suitable size and use details view. Close it. 1) Run 'dolphin /usr/bin' 2) Scroll to the bottom of this details view. 3) Click compact view. 4) Click back to details view. Results: Details view is now blank - no files showing. Number of files shows up in status bar at the bottom, and there's plenty of white scrolling space, but nothing is shown. Bonus: 5) Now click on icons view: same thing (blank) but lots of scroll space as if there were something to see.

I can confirm this behavior with Dolphin 17.12.3 on KDE Neon User Edition. I'll change the status to CONFIRMED. Thanks for the detailed report!
Also reproducible with Dolphin 18.04 on Arch Linux.
Can confirm still an issue in 20.08.1

Note to comment 5: Scrolling to the right is sufficient to trigger the bug. No need to select any files. Reproducible: Always.
Created attachment 150404 [details] Screenshot: Details View and Icon View shifted to the right by an empty column To comment 5: Depending on how much it was scrolled to the right: It may happen that the content of the folder in the "Details View" and "Icon View" is still visible, but a _wide extra empty column_ was added on the left, making all the content shift to the right. Thus it looks like a wrong origin or offset is used when rendering the content and in the extreme case, the content becomes completely rendered offscreen.
Created attachment 150405 [details] Screenshot: Icons View: Content is shifted to the right out of the window In this screenshot you can clearly see the content is shifted to the right and part of it is rendered outside of the window. If I make the window big enough (by spanning it over two screens and zooming out), I can in principle make the whole content visible again.

Git commit 0e4d428e84099bf5d76e81640a2417d5457d83a4 by Amol Godbole. Committed on 05/09/2023 at 06:58. Pushed by meven into branch 'master'. DolphinView: Reset scrollbars before changing view mode When view modes are changed, the scrollbars are not reset. This can cause the scroll area to be moved out of view after changing the view mode, making the view unusable. This commit resets the scrollbars.
