Public bug reported: Dolphin takes ~7+ seconds to start after launch. It appears to be spinning on scanning for DRI devices. It is not io bound or cpu bound, it's just doing a lot of scanning of the file system for what appears to be rendering devices (out of my element here) and it REALLY shows up as a delay on a pi device. This is a 4b with 8 gig of ram and I can verify that this behavior is not in debian stable but is present in debian testing (when I shoehorned it in on, lol), and from what I can tell, the same thing happens on my x86 machines, but they're just so fast in comparison that this doesn't show up. Strace logs are attached. I also reported this directly to the KDE team (not ubuntu) as I'm not sure if this is a software or setup thing.
