Steps To Reproduce:	Ubuntu 9.10 with GNOME as shipped, latest SVN. 1 Generate a tone of 30 seconds and hit Space to play it. 2 Follow the playback cursor and click in the waveform behind the playback cursor, then CTRL + B and start typing 3 Each keystroke creates a vertical line in the waveform at the current playback position 4 Same issue if you CTRL + M instead of CTRL + B 5 The same issue appears to be there when you type in a label while recording, but the spurious lines disappear at once. 6 The spurious lines always disappear when you press Stop.
Release Note:	(OS X and Linux) Typing in a label while playing draws temporary spurious lines at the playback position.

Bill sees this on Mac OS X too, but without the drawing of grey bits in the yellow focus border that he sees in Bug 255.

Applied Roger's patch for Bug 255, which calls Refresh() on the whole TrackPanel rather than trying to do so for only the rectangle that needs it. 

He says this should also fix Bug 148.

Please test whether it's too much of a performance hit, here and Bug 255.

Comment 3 Gale Andrews 2011-02-25 04:30:15 UTC

Don't see the spurious drawing on Ubuntu now.

Don't see any performance issues on Win 7 x64 or Ubuntu compared to 1.3.12 release, testing on up to five tracks.  

Needs Bill's input otherwise looks like it could be resolved-fixed.

No spurious drawing with 1.3.13-alpha March 4 on PPC Mac 10.5.8. No noticeable performance hit with 3 mono tracks and 2 stereo tracks.

Comment 5 Gale Andrews 2011-03-06 02:08:07 UTC

RESOLVED - FIXED. Thanks for testing, Bill.
