ANGLE: Scaling at Waveform resize not always correct #12608

Bug Description

I tested the latest Mixxx 2.4 with ANGLE, by setting $env:QT_OPENGL = 'angle'. The waveform scaling was not working properly if I move the window splitter fast:

OS

Windows 11 + ANGLE

Does the issue also persist across restarts or is it only an issue while resizing?

JoergAtGithub commented 10 months ago

The issue hapens only with ANGLE (OpenGL ES to Direct3D 11 translation): ES OpenGL ES 3.0.0 (ANGLE 2.1.5414 git hash: aa63ea230e0c) (ANGLE (AMD, AMD Radeon(TM) Graphics Direct3D11 vs_5_0 ps_5_0, D3D11-31.0.21024.5005)) It does not happen if I use the native OpenGL driver: 4.6.0 Compatibility Profile Context 23.10.24.05.230830 (AMD Radeon(TM) Graphics)

The waveforms scale only wrong, if I reduce the size, they are scaled correct as soon if I increase the size.
After restart of Mixxx the waveforms are always scaled correct
The problems only occurs when I reduce the size of the waveforms fast, if I move the mouse slowly, everything is fine.
