At some point after an update, launching that app would take multiple seconds. How could the most basic gtk app be so slow to launch.
Investigating further, I found the update had transformed the normal gcalc package into a snap, probably just to prove how great snaps could be for desktop apps?
What a bad way to introduce your latest tech canonical. From then on, my opinion of snaps was very negative and I still do everything possible to avoid them. Even if they are technically great or more secure, canonical messed up their introduction and are now stuck pushing a dead horse.
