SUMMARY Theme icons are not applied when Dolphin runs **outside** of Plasma DE. I've tested Hyprland. Within Plasma, no problem. 24.05.2 is the last version of Dolphin that worked and downgrading to this version fixes the problem! I've confirmed this bug with other (Hyprland) users. STEPS TO REPRODUCE 1. Set custom icon theme 2. Start Hyprland 3. Start Dolphin OBSERVED RESULT Default icons are shown EXPECTED RESULT Custom icons should be shown SOFTWARE/OS VERSIONS Operating System: Garuda Linux KDE Plasma Version: 6.1.4 KDE Frameworks Version: 6.5.0 Qt Version: 6.7.2 Kernel Version: 6.10.7-zen1-1-zen (64-bit) Graphics Platform: Wayland Processors: 24 × AMD Ryzen 9 5900X 12-Core Processor Memory: 62.7 GiB of RAM Graphics Processor: NVIDIA GeForce RTX 4080/PCIe/SSE2 ADDITIONAL INFORMATION
Can confirm on Arch and Gentoo with AwesomeWM. Downgrading to 24.05 solves the issue.
