Nothing is throttling my CPU unless it’s somehow defaulted on in OpenSuse, Manjaro, Debian, or Linux Mint. Also these same distros, I installed other DEs on and had it work just fine. It’s a AMD Ryzen 9 3900x 4 ghz 12 cores.
This is specifically a KDE problem. So question, if you do windows key -> term/kon -> enter. As quickly as you can, does it accept the enter input and immediately launch your terminal?
@MJBrune@Ashiette I tried doing it as quickly as I can and it didn't work the first time (result appeared what looks like about 0.1-0.2s later) but it did work in subsequent attempts (even when looking for other apps)
CPU: i5-1135G7
If you look for an app and then for a different app, does it find it quickly? I suspect it might be reading the .desktop files lazily (meaning it only reads them the first time you look for something)
Edit: nvm ksycoca is there to prevent that
Even if I look for the same app over and over again, it doesn’t speed up. Doesn’t seem like a caching issue to me. Perhaps the second time you were just .1-.2 seconds slower on the enter button?
