Back when the same question was asked about plasma 5.25 from unstable to testing
Now that is on both unstable and testing branches and did more tests, personally i still think is not there yet, and upstream fixes need to be applied.
I really wish this list will get slimmer
- 45 15-minute Plasma bugs (down from 49 last week). Current list of bugs
- 20 Very high priority Plasma bugs (down from 21 last week). Current list of bugs
- 121 KDE bugs of all kinds fixed this week. Full list of bugs
