Every now and then, track view resizes itself to be "tiny box", without anyway of resizing to fill whole area. I.e. other component containers stay in place (bottom and left), but track view won't be filling whole area available for it. Trying to reset or change layout doesn't seem to fix, and so far I've found out only that program restart seems to be fix for this. This is rather problematic, since when this bug is hit (seems to be reasonably frequent), all the playback controls are also lost of course.
