Description Norman Back 2021-10-31 17:44:16 UTC
In summary:
kde-frameworks-5.82.0 allows changing folders within dolphin and kate, without any freeze.
Using kde-frameworks-5.85.0 and kde-frameworks-5.87.0 results in a 20 sec freeze when changing folders 
within dolphin and kate.

I upgrade kde to the lastest stable release on 13th Sept 2021. Everthing seemed to work OK at first but
I later found that when I use dolphin or kate the application freezes for 20 secs when changing to a diffent folder.
I downgraded the whole of kde to the release in use prior to the 13th Sept 2021 and the issue disappeared, confirming that 
the problem was in the lastest stable release of kde.
After some thought I upgraded all but kde-frameworks to the lastest stable release of kde leaving 
kde-frameworks at 5.82.0. There was no 20 sec freeze.
Wondering if the unstable kde-frameworks 5.87.0 might also be OK I upgraded to that but the freeze returned.

I also noted that when starting dolphin from the command line with kde-frameworks-5.85.0 a large number of errors were
reported on the console. However kde-frameworks-5.87.0 did not maifest this so is not relavent to this issue.

Reproducible: Always

Steps to Reproduce:
1. Install kde-frameworks to 5.85.0 or
2. Start dolphin

Actual Results:  
1. switch selection between two folder containing a large number of files/folders
2. observe the freeze ( 20 secs on my box ) before dolphin is responsive again.

Expected Results:  
1. switch selection between two folder containing a large number of files/folders
2. no freeze occurs.

During the 20 second freeze, high IO ( > 50% ) can be observed on many hard drives via atop.
