GLSL waveform renderer not rendering until renderer is changed on macOS

[Foss-4]

macOS 10.13.6
mixxx 2.3.0-alpha-pre (build master r6770)

Reproduce

- load track and play

Curently

no waveform is displayed. oddly enough after switching waveform display from RGB (GLSL) to RGB (GL) and accepting with "ok" waveform is displayed.

now the interesting part is, when switching back to RGB (GLSL) waveform is also displayed. so the problem is not that RGB (GLSL) is completely broken.

the problematic behaviour can be reproduced with all skins.

Starting mixxx with RGB (GL) works fine. The issue is limited to loading mixxx with RGB (GLSL) pre-selected.

is this a dupe of this bug here? https://bugs.launchpad.net/mixxx/+bug/1825461

Please add the mixxx.log from a test run
* start with GLSL
* switch to GL
* switch back to GLSL

is Mixxx 2.2.0 effected as well?

I think not, bacause here waveform data and overlays are missing.

macOS 10.13.6, MacBook Pro late 2011

Testing 2.3.0-alpha-pre (build master r6770)
log for: started w RGB (GLSL), switched to RGB (GL) and back to RGB (GLSL)
log for: started w RGB (GLSL) played track -> no waveform showing up

Testing 2.2.0 r6659 (stable)
not reproducible -> regression in 2.3.0

I can reproduce this with my friend's 2017 Macbook Pro running macOS 10.14. 2.2.1 is not affected.

There is a chance that
https://github.com/mixxxdj/mixxx/pull/2088
fixes this issue as well.
Please try it out.

I think this is finally fixed with:
https://github.com/mixxxdj/mixxx/pull/2105
Please verify.

no edit function :/

this is in the 2.3.0 milestone while the commit is tagged with 2.2.2 on github. is that correct?

[Daniel Schürmann (daschuer)]

In this case we can target the bug to both series.
