Linux/Mac: Incorrect rewind on Play
Last modified: 2020-03-01 17:16:44 UTC
1) Generate a 30 second chirp. 2) Set the Play cursor to 3.0 seconds 3) Zoom in so that you can see from about 2.5 seconds to 5.5 seconds. 4) Press Space to start playback, and again to stop playback after the screen has scrolled (say at around 8 seconds. 5) Press space again to restart playback. Expected behaviour: Audacity rewinds so that the start of the selection (3.0 seconds) is visible on the track, and starts playing with the start of the selection visible. Actual behaviour: Audacity rewinds so that the start of the selection (3.0 seconds) is at the start of the track, and immediately jumps back a bit so that the start of the selection is hidden to the left of the beginning of the track. Confirmed on Windows and Linux. Assumed all platforms.
WORKS FOR ME on Windows. Please improve/refine steps for windows.
Testing on W10 with audacity-2.3.3-alpha-305-2b15aa28cacf9f50722b054b31291ace85945b00 Confirm WORKS FOR ME on Windows too.

The "strange little jump" is a fairly new phenomena. >The fact that playback start position (3.0 seconds) is off-screen, is older >and goes back to at least 2.2.1.

Works fine still on my W10 with audacity-2.3.3-alpha-313-5ebc13be93dd5a740887ae558aca8f69a1fdfd0d But on my Mac with latest jc005 alpha I see a little jittery jump when the cursor gets to the right end at 3.7 seconds and has to repaint - all subsequent repaints go smoothly as usual. So this is looking like a Mac/Linux bug - and I have marked it accordingly
