It might be just me, but at some point in the last 1-2 years, all the #KDE apps I use on my #Librem5 got noticeably slower. This includes #PureMaps and #KDEItinerary. It feels like some sort of graphics acceleration shenanigans: Map scrolling in PureMaps used to be smooth, and now is almost unusably laggy. Even just scrolling up and down an itinerary or pushing a button is slower than a comparable GTK app (Tuba, Gnome Maps, etc...).

Oh great and powerful hive mind: How might I seek out incantations that could fix this?

@okennedy Is that about Flatpak apps on PureOS? If so, then this is now fixed on crimson (but not on byzantium and it will probably stay broken there).
@dos Yeah. Flatpak on PureOS. Some sort of limitation on sandboxed access to the GPU? (something I might be able to work around with a native build?)
@okennedy Incompatibility between Mesa versions inside and outside the sandbox.
@dos Ah. Thank you! That explains a lot.
