[MU4 Issue] Score extremely zoomed in when opened

[lordlouckster]

Describe the bug
Sometimes, when you open a score, it opens extremely (but not maximally) zoomed in from the top left corner.

To Reproduce
Steps to reproduce the behavior:

1. Open a score. This should open correctly.
2. Open another score using "Open" in the window of the aforementioned score.
3. The score opens zoomed in.

Expected behavior
The score should open like the first score when following the steps.

Platform information

• OS: Windows 10

Additional context
This issue can be mitigated by reverting to factory settings, but it may or may not occur again, and once it occurs, it won't go away until you revert to factory settings.

When it happens again, could you please check what Preferences > Canvas > Default Zoom says? Or have you already checked that and didn't it say anything special?

I've no luck reproducing this so far...

[lordlouckster]

Default Zoom didn't say anything special. A risk factor of this bug seems to be a jaggy scrollbar.

[lordlouckster]

I've reproduced it a couple of times, and there seem to be presymptoms when opening the navigator, which causes the scrollbar to stutter under certain circumstances, possibly including additional load from background applications.

[cbjeukendrup]

Ah! The navigator! That might be it indeed. I'll take another look to reproduce it!

Just came up again in https://musescore.org/en/comment/reply/node/348567. Oddly, the first score opened in any given session is normal, but opening a second instance shows the problem. That's the case in the video from the OP in that thread, also on my system. The Zoom control shows 0% which is obviously bogus, but score is way zoomed in. My display is not large - just an ordinary 13" laptop (Linux, on Chromebook).

@lordlouckster Does this still happen in the MuseScore 4.1 nightly builds? https://musescore.org/en/nightly-builds

Still can reproduce 0% zoom with opened navigator
OS: Windows 10 Version 2009 or later, Arch.: x86_64, MuseScore version (64-bit): 4.2.0-231952157, revision: github-musescore-musescore-3817022

[Jojo-Schmitz]

I still can reproduce too, even in 4.2.0, in all parts, but not in the main score

I have Edit > Preferences > Canvas > Default zoom set to Page width.
Works for the main score, but for all parts it is set to 0% (in the lower right corner), but clicking on it does show Page view, this isn't honored though but shows the part(s) very large instead
I do have the navigator open too, and that seems a contributing factor, as it works properly without

[dcorson-ticino-com]

This is apparently provoked by the Navigator.
W/o Navigator all is well, with the Navigator parts are displayed wrong.
I have Preferences>Canvas>Default Zoom set to 100%, but my parts always open to zoom 0 according to the drop-down in the lower right corner. The displayed part is, however, is at somewhere between zoom of 200 and 300 (255?). I can set the zooms of the parts to 100% and they display correctly, but after saving, closing MU and opening again all is back to 0. The score is behaving, it is just the parts with this problem.

Closing as superseded by #23033. That one is actually a duplicate, but is much clearer and doesn't have a long comment history yet, so I'll close this one instead.
