Today I encountered a strange behavior of grasshopper I have never encountered before.
I built a definition that worked fluently, without any problems. After closing Rhino/Grasshopper and opening the files again, when i place any component on canvas I get about 1-2 second lag.
That happens without connecting said components anywhere - just dropping them on canvas (and any other action, including connecting them later) causes a short “freeze”.
I found out that turning to “Don’t draw any geometry” fixes that problem.
Interestingly enough, when I have any of the “Draw preview geometry” selected TOGETHER WITH “Only draw selected objects” (with no components selected - so I basically preview nothing) I still get the “lag”.
Canvas redraw speed is high: over 180-250 FPS
Autosaving is Disabled.
I know this description is kind of messy, please pardon my english. I recorded a short video that presents the problem:
