Bugzilla – Bug 2389
At some zoom levels the light-blue/white selection visual cue disappears
Last modified: 2020-04-22 04:46:11 UTC
At some zoom levels the light-blue/white selection visual cue disappears - this means that the user can have a selection present with no indication in the waveform that there is such a selection. The only visual cue is in the Selection toolbar but that's very easy note to notice. Whatever the zoomed out level that should always remain a residual 1px or 2px light-blue/white line in the waveform. Note that in Spectrogram view it would be a black line.
Please add a release note, or demote to P4. This bug (actually it's a valuable enhancement request) is not going to be fixed for 2.4.0
I relented. DEVEL - FIX MADE https://github.com/audacity/audacity/commit/9ad06aeeb16b8d2f96f805433cf34a2a8197c488
(In reply to James Crook from comment #2) Tested on W10 and macOS 10.15.4 with Audacity 2.4.0 9ad06ae This looks good on both platforms/ 1) imported a 5 minute song 2) zoomed in to sample level 3) select a single sample 4) Zoom to fit 5) Observe selection thin white line shows
restoring this to its original P2 status so it gets more prominence in Release Notes and What's New...
There is a residual case where the white line becomes invisible still with a selection at the right hand border of a track 1) get a 3 minute song 2) zoom normal 3) select a second or so at the far end 3 mins 4) zoom to fit 5) Observe: thin white line still shows (and carefully observe thin black line end of track marker beside it). 6) Zoom out 2 or 3 times (YMMV) 7) Observe: the thin white selection line disappears My suspicion is that at these zoom levels the white line is hiding under the thin black line end of track marker. 8) Zoom in a few times and watch the white selection line reappear This does not happen with a short selection at the beginning of the track - even if the track does not start at T=0 Are we bothered about this fringe case ?
Fringe case is rare enough we don't need to log it. It is possible there are other cases like yellow snap markers etc. The main problem is solved. With sync-lock even quite long clock-sections may not be visible, but that is a different issue. Just noting it, should we ever wish to revisit and prioritise the different kind of markings when things overlap.
There is a further residual in that the thin residual selection line does not show in Spectrogam view (or the Spectrogram in Multi-view) More of an issue as we now have Multi-view as a key new feature for 2.4.0. Tested on all four themes and this is true with all of them - the line shows in waveform but not in spectrogram.
Created attachment 963 [details] Short selection in Multi-view Here we see the white line for the short selection present in the waveform but not in the spectrogram. In contrast if we make a longer selection (or if we zoom in) it will show in both the waveform and the spectrogram.
(In reply to Peter Sampson from comment #8) Testing on W10 and macOS 10.15.4 with eb92fc0 This residual has now been fixed with commit https://github.com/audacity/audacity/commit/20ba353038edbd49a510dcdb72e0a88257eec79b The line for the short selection is now present in the spectrogram (and multi-view) black of course rather than white plus a thin sliver of the actual spectral selection.
