When I alt-F2 to open krunner and use it to start applications, it usually (maybe 75-90% of the time) will start consuming 100% of a CPU. krunner still works, but a core is running constantly in the background, the CPU cooler fans spin up, etc. To trigger the bug I don't need to actually start anything, I just start typing and it searches through it's guesses, etc. A bit of that, opening closing the krunner window, etc, will usually make the thread go to 100% usage. If I go into settings -> Plugins: Configure Enabled Search Plugins... -> Recent Files and disable it, then Apply, the core drops back to normal and everything works fine. No other plugins seem to cause any problems, just Recent Files. $ kinfo Operating System: Kubuntu 24.10 KDE Plasma Version: 6.1.5 KDE Frameworks Version: 6.6.0 Qt Version: 6.6.2 Kernel Version: 6.11.0-9-generic (64-bit) Graphics Platform: Wayland Processors: 8 × Intel® Core™ i7-4770K CPU @ 3.50GHz Memory: 15.5 GiB of RAM Graphics Processor: NVIDIA GeForce GTX 1060 6GB/PCIe/SSE2
