I just installed Manjaro KDE yesterday and everything is going great, except one particular problem. All the KDE apps start horribly slow. Dolphin, Konsole, the Settings Manager, almost all KDE apps start slow (Dolphin often takes 15-20 seconds to start and Konsole takes 5-7 seconds). Once started, everthing runs smooth. All other apps start pretty fast. I've tried most solutions I could find (tweaking compositor settings, changing QT_GRAPHICSSYSTEM to raster etc.) and nothing has worked so far.
When the apps start, the window is transparent, if I move the window, it moves showing whatever was in the back previously (like taking a snapshot).

Sounds like you need an SSD drive. Please post your specs:
@tbg I do have an SSD although my /home is mounted on an HDD. The SSD is used as root. Here's the output of

I don't know if it's just placebo but my pc just woke up form hibernation and it seems way snappier.
You shouldn't need to use preload with an SSD and a computer that new. I would think something is not quite right with your setup. My computer is 10 years old and I've never needed preload with KDE on Manjaro. You shouldn't need it with your system if things are working properly.
@tbg Seems logical. How can I go about finding what's wrong though?
@tbg I've tried disabling baloo before. Didn't make any difference. What worked is preload. Also, it seems better after waking up from hibernate (even better than a fresh boot). I don't understand this at all.
Well that's what preload does. It gives you faster startup times on your programs by caching them, but it shouldn't be required on modern hardware.
Well, I only know it hasn't been used by recent installs by default as it was felt it was no longer needed. I'm not saying it doesn't serve a purpose, it just shouldn't be required on a normal install on modern hardware.
He shouldn't be experiencing those delay times. Preload obviously helps with that, but it shouldn't be happening in the first place is all I'm saying.
Before you go all full out changinging your video stup install htop. It is a terminal app, start it in terminal.
What is your cpu usage like and what are the things at the top of the list for using resources.
Personally I would not put your home on the platter drive. That negates half the benefit of having an SSD IMO. Have your home partition on the SSD and symlink your large storage folders such as Video into your home directory.
But that never caused problem in any other distro. All of them were debian based though.
How fast is the drive and is it internal.
It is internal. What do you mean by how fast? I've achieved speeds over 100 Mbps while copying from an external drive (also HDD).
Is it a platter drive 7200rpm. SSD is still way faster.
That's to be expected. I meant it's not too slow.
Anyway, to those who faced a similar problem, I solved the problem by moving
/home to my SSD and symlinking big folders from my HDD. Thanks to @tbg for helping me out.
