I’ve been running Plasma Mobile on my Librem 5 and it’s pretty snappy though I’m not sure how viable it will be as an app platform as KDE has chosen to rewrite all their core apps using a more mobile friendly framework. So there isn’t a whole lot to dive into and probably won’t be for a few years still. I will give sxmo a try from your recommendation.
Yeah I think I ran an early build on a Pinephone and it was laggy. I’ve heard if you go Pinephone you have to go with the Pro version, because the previous model has no hardware support. Thus the poor quality software experience. Purism actually contributes to the software side so while it’s a bit lacking in quality, it is getting better with snappier ui and battery life.
The problem with Kirigami is that it became a grab-bag of missing Qt QML components that relies on Qt Fusion-styling instead of a unique design language as originally proposed. So the migration to v6 doesn’t really benefit, because Kirigami just inherits bugs from Qt QML which may or may not still be present.
Yes it is more of a QT thing because they didnt update widgets for mobile friendliness but I didn’t want to go into the details as it wasn’t my point. I’m not really a fan of QML so I am not sure I’m going to stick with Plasma Mobile anyways.
