simple RGB, HSV & Filtered waveforms not scrolling on macOS

Can you please test with Deere and Tango which renderers are affected?

Deere:
affected: Filtered, HSV, RGB,
ok: Simple - Qt (GL), Filtered - Qt (GL), Simple (GL), Filtered (GL), Filtered (GLSL), RGB (GL), RGB (GLSL), HSV - Qt (GL) ping overlay with pink waveform - that expected? but it scrolls, RGB Qt (GL)

Tango:
affected: Filtered, HSV, RGB,
ok: Simple - Qt (GL), Filtered - Qt (GL), Simple (GL), Filtered (GL), Filtered (GLSL), RGB (GL), RGB (GLSL), HSV - Qt (GL) ping overlay with pink waveform - that expected? but it scrolls, RGB Qt (GL)

Deere + LateNight + Tango:
affected: Filtered, HSV, RGB,
ok: Simple - Qt (GL), Filtered - Qt (GL), Simple (GL), Filtered (GL), Filtered (GLSL), RGB (GL), RGB (GLSL), HSV - Qt (GL) ping overlay with pink waveform - that expected? but it scrolls, RGB Qt (GL)

Shade:
all waveforms ok

So now all skins except Shade are affected???

Can you still reproduce this?
Or was there a mac update maybe?

2.3-beta-4131-g5ae08b96de on macOS 11.4 persisting.

This is kind of being wokred around already since the default waveform renderers are not affected, and when Mixxx crashes during skin because an affected renderer is selected that wouldn't be stored in the config, so it can at least be restarted without issues.

First I thought that might be caused by waveforms being loaded in Singletons, but that's not the case for affected LateNight (and not necessary in Tango btw).
Then we had Deere previously crashing on macOS if spinnies and waveforms were in the same singleton. But that's also been changed.
Back then, one conclusion was that reparenting the singleton caused issues with the GL context.

So it seems skins are affected as soon as ANY GL widget is loaded into a Singleton.
Solution would be to load individual instances of spinnies and waveforms in every skin, but that would defeat the purpose of saving memory only for getting the simple renderer to work on macOS.

Given the fact (assumption?) that the computers running the minimum supported macOS version 10.12 are powerful enough to not require the simple renderers for performance reasons we can simply hide them on macOS -- and switch to another renderer in case a simple renderer is stored in the config after upgrading to 2.3.

What do you think?

I agree, Apple laptops have had good GL for at least a decade, I can't imagine a situation where the fallbacks would be needed on that OS

oki, I'll prepare a PR

it's not fixed, just ignored and hidden for now ;)
