If i start PowerApps Studio right after i boot up my Surface Book I, everything in the PAS UI is snappy, and it's a delightful developer experience.
But if i keep using PAS for a couple hours, things start to get sluggish. If i open Outlook and/or Visual Studio all at once, things go downhill faster. By then, i might as well go get another latte in between typing sentences or clicking PAS controls.
Memory after bootup is around 53%. with the big three apps running and Microsoft Teams running too, i've seen memory climb into the 90%. If i shut down those memory hogs, memory goes back to "normal" (but PAS never recovers it normal speed in the UI)
I just noticed one other side-effect that made my heart stop:when i reopened PAS without restarting the Surface Book, most of my day's work today was gone, even after PAS warned me there was unsaved work (even though i had been saving all morning, including right before i hit the close button a few minutes ago).
but when i opened my App in PowerApps Web, everything seemed to be there, and i started breathing again. This reminds me of my authoring days back in '96: everytime i tried to add a comment to my manuscript i was writing in Word, Word might crash; so i created a macro that saved the doc with each new comment.
this does not inspire any more confidence in my tools today than it did all those years ago...
