Just switched to ver. 16.2.18 revision 46383 under Linux Mint 18.1 (4.4.0-57-generic) from a similar setup (Linux Mint 17.3, 16.X.XX version of Brickscad).
I am noticing arbitrary zoom in/out and panning while picking points during a command. Minor artifacts (e.g. lines) may also appear some of the times.
Has anybody else faced this problem?
