Sorry, but as an early adopter of Plasma 5 (granted, maybe a bit too early), it was terribly broken for a couple of months. I took refuge in Awesome until things stabilized.
Huh. I started using Plasma 5 on a bleeding edge rolling distro and it was just fine. Everything was a mix of KDE4 and KDE5 apps for a while, but they all worked with minor quirks at worst.
I believe I was switching between Arch and OpenSUSE at the time, and I didn't note down specific issues, I seem to recall problems with kwin dying... maybe something to do with multihead? If I'm not mistaken I was still using a PC with a Radeon HD 7770 GPU at the time (for all the Catalyst issues I've had, still one of my favourite pieces of computer hardware I've ever owned), so it could have been iffy interactions between moving parts. I do seem to recall a period when I got many, many panics (or oopses, I dunno, screen went black and nothing reacted to anything), I think that was around the same time.
Forgive the vagueness, but I don't believe in memories and haven't kept a journal. Still, as completely unreliable and untrustworthy human memory is I am inclined to believe I had issues with Plasma 5 during the transition period.
Yeah, I'm sure you did run into real issues. I was trying to figure out if they were distro issues, or if issues that also affected me were more of a problem for your workflow than mine, etc.
Either way I think that still sounds better than the old 3->4 migration, and hopefully 5->6 can be better still!
I can see that. For me personally about a year~ish ago Plasma Wayland reached the point where it's good enough for me to use as a daily driver...
...though I do lament the loss of Desktop Cube.
Of course, coming from Awesome I am often annoyed at how Plasma doesn't have per-screen (X11 monitor, if I'm not mistaken) tags and per-X11-display workspaces don't really work that well.
What were your issues? What was the distro?
