Very slow keystroke response Edgeline v0.3

On both Windows 10 and Ubuntu 16.04 (Unity Player), and am getting very slow keystroke response when I try to rename objects or change Text values (labels, etc). It’s like being on a very slow ssh connection to server on the other side of the world.

Is it the same with a new, empty UI with only 1 label widget?

No. I just tested on Ubuntu 20.04.
With a single label there is no keystroke delay when changing the label name or the label text content.

In the beta there is bug with the history. If it gets to long it starts to consume a lot of memory and probably it causes the slow down.

Of course in v1.0 it is fixed.
