GLSL Waveforms disappear on resize

[tgucio]

Bug Description

When resizing the window on a large 4k display on a MacBook Pro M1, beyond certain size the waveforms disappear:

HW: MacBook Pro 14", 2021 (Apple M1 silicon), macOS Ventura 13.4.1 (c) (22F770820d)
Mixxx version: 2.4-beta-70-g2e3d72f479

Version

2.4-beta-70-g2e3d72f479 (Apple silicon build)

OS

macOS Ventura 13.4.1 (c) (22F770820d) (Apple M1 silicon)

@m0dB Could you've a look

Hi, I am on holidays and not near a system where I can try to reproduce this. @tgucio are you building mixxx yourself and able / willing try out some things? I would like to know which of the layers (aka renderers) that make up the waveform display cause this issue. But first of all: does this happen with all waveform types?

[tgucio]

@m0dB The problem with building is that I don't have an Intel silicon Mac to build on - I take it building on M1/M2 is still not supported officially (I'm getting some failures building fwcd/m1xxx now).

I've experimented a bit with waveform types and here's what I see:

NOK:

• Filtered (GLSL)
• RGB (GLSL)
• RGB Stacked (GLSL)

OK (not reproduced):

• Filtered (GL)
• Filtered (all-shaders) (GLSL)
• RGB (GL)
• RGB (all-shaders) (GLSL)
• RGB L/R (all-shaders) (GLSL)
• Simple (GL)
• Simple (all-shaders) (GLSL)

Another data point: Can't reproduce on
macOS 13.5 (Intel mac)
2.4-beta-75-gc3df3da55d
Tried all three NOK waveforms and resizing on an external 4k monitor.

Seeing that the "all-shaders" waveforms behave fine, I don't see a reason to investigate this further. Instead, we should just recommend (and default to) the all-shaders waveform types, at least on macOS.

We will remove the legacy GLSL Waveforms soon.
