UI: Reverb slider off-center in MacOS as of 3.9.0 / Qt6
Discussed in https://github.com/orgs/jamulussoftware/discussions/2768
Originally posted by rdica August 1, 2022 This was first reported to me from an associate using Jamulus 3.9.0 MacOS Monterey. I upgraded my client on MacOS Catalina and see the same thing, the reverb slider is off-center.
No issues on Ubuntu 18.04 with QT 5.9.5.
Jamulus 3.9.0, QT 6.3.1, main MacOS build. (I installed the legacy dmg, it runs on MacOS Catalina and it does not display the reverb slider off-center. Its QT version is 5.9.9.)

@rdica Thanks for the report. This sounds like this unresolved Qt bug: https://bugreports.qt.io/browse/QTBUG-98903 :(
I guess it might be possible to find workarounds by adjusting specific style options or painting manually, but I'm not sure if we want to do the latter. It would also be good to have someone on Mac OS develop/test this fix as this would certainly benefit from a tight feedback loop...
I'm adding a 3.9.1 target for now, but it might well be possible that we'll have to postpone it until a fixed Qt version is available.
I tried each skin and the reverb slider was off-enter in each.
@rdica Could you please also check the other faders in the settings dialog, are they affected as well (network buffers, input balance; screenshots would help)?
@rdica Two other things to try (not really expecting an improvement though...):
@hoffie Apologies for the delayed response....I tried both builds, using all skins, same results; still off-center.
Screenshots of Settings dialog faders each of 3.9.0, and the two dev builds:
3.9.0
3.9.0dev-d95ebaa
3.9.0dev-e08c36b
Thanks for the feedback! So somehow the technically similar faders in the settings dialog are not affected. I'll try to dive into potential differences.
Sorry, did I miss something, the sliders in the above screenshots look off-center, same as the reverb slider...
Hmm, sorry, I seem to have missed some details. I do see a slight mis-rendering of the knob (the ticks on the left are less overlapped by the knob compared to the right), is this what you mean? Or do you mean the layout of the whole slider, which seems to be slightly off compared to the header text?
OK, so 5.15.2 has the issue on Windows 10.
Do we have anyone able to look into the cause on this? I'd like to know where the bug was introduced. @hoffie, as it's likely to be some change to the build dependencies, is this something you could pick up?
It's worth a look at the screenshots from the issue mentioned above. It could be more evidence the issue isn't the Qt version itself but somewhere else in the build process.
