Ok, hopefully this is a more reliable way to reproduce the bug for you:
- Create a new .Rmd from the menu (I use the little icon, but both 'work')
- Click OK (all default)
- Go to line 29
- press ctrl+alt+i
- type:
blah %>%
mutate(blah = blah) %>%
filter(x != y)
-
select with mouse, press ctrl + c
-
click line 35
-
press ctrl+alt+i
-
press ctrl + v.
Cursor still flickers, but can no longer do anything in R.
This breaks Rstudio around ~ 75% of time. If it doesn't break, then press ctrl + alt + i, and paste again... eventually it breaks for me.
