In a game against the computer, sometimes, the first shot is partially transparent and stays that way during the whole match. Reproducible: Sometimes Steps to Reproduce: Repeatedly start a match against an ai opponent, just till you have done your first shot. If the bug does not appear, repeat. On some days, I hit the bug in about three of four games, but sometimes it takes about 20 tries to trigger the bug.

Jaime Torres fixed this while implementing a new feature. Code is on master and will be shipped on KDE's next release.
