1) Its becomes veeeeery slow on usual files, which was previously ok. Especially scrolling, if someone have a good mouse, like Logitech with "free wheel" it just unacceptable. Much slower than in previous IDE versions.
2) Also, which is however less important, non-usual Unicode strings like: //1= 2=︎︎︎ 3= 4= 5= 6=︎ will kill the IDE if someone will try to select the line, especially in block selection mode (Alt+Shift+Arrow).
i'm more disturbed on its freaking slowlyness when changing to "free window mode"... is the ide all drawn on canvas?
I must say that I haven’t experienced any slowdown in the editor response. In fact switching between form and code view seems significantly faster.
