I have a layout that displays five labels and a bar graph. I would like to update several times per second, but Layout.update takes about 0.22s to complete. Is this normal? Changing fonts from vector to bitmap did not change anything.
As a workaround i just use g.clear() and redraw the layout completely in 0.12s. This way, i can call Layout.update just once, but then text alignments are messed up. Turns out layout uses update to calculate the position and size of a text label, then draws the text centered into it.
I think layout should use g.setFontAlign with the correct alignment to align the labels, one call to layout.update would then be enough for many apps (where you usually don´t want your layout to change because a number is now two instead of one digit).
