I created a ScrollPane and placed a Pane inside it. I added 100k Text instances to the Pane, and placed them in such a way that about 1200 would be visible at the same time on the screen. As there were 100k Texts I could scroll a lot (vertically). This was very fluid when using FontSmoothingType/GRAY. But as soon I switched to FontSmoothingType/LCD this was extremly much slower.
Please improve the performance of LCD texts.
