--- Comment #2 from igor....@protonmail.com --- I haven't experienced this problem during regular non-root usage. I've managed to boil the problem down a little bit more. It doesn't matter who owns the directory, it's only about copying a file from a non-root Dolphin instance to a root instance. I did a few more experiments: 1. I tried copying a file from a non-root owned directory opened as non-root to another non-root owned directory opened as root. It was slow. 2. I tried copying it back. It was fast. 3. I tried the same, but with both directories opened as root. It was fast. 4. I tried copying a file using a single instance of Dolphin opened as root. It was fast. -- You are receiving this mail because: You are watching all bug changes.
