I've noticed that during the begining of the game - during hero choosing phase - the tooltip of the skills is not on top.
Specific bug - the tooltip of Ancient Ice Frog' skill is below the tier 3 icon. Aquadillo as well.
Great catch! We've caught the cause of the bug and slain it forthwith. Thanks for the report!
Another tiny UI bugism - a bit annoying when playing with the options in the native client. The dropdowns at the bottom of a visible window (I suggest Graphics tab, because it has lots of dropdwons) has its items showing in the non visible area of the window.
The dropdwons are not wide enough and longer strings are drawn into the small triangle area.
In the hero picking screen. Units that have a name 2 line long and description 3 line long - the text overlaps. Example - Bramblethorn Goliath.
Toxin Alchemist - description does not say if it is melee or ranged.
Trebuchet, Conduit - description longer than 3 lines, does not fit the window.
