no scrolling waveform on startup on Windows

[rafaelfrench]

Windows10, 2.3.0-alpha-pre (build master git7242), Tango Skin.

The Waveform summary doesn't show nothing. To see the attached video.

I had the same bug since git7233.

I assume this was related to the problem with OpenGL and Qt5.

Mixxx 2.3 beta should have a workaround on Windows for this, even though it was a less-than-ideal solution.

Could you verify if that works for you?

Is this still an issue with recent Windows builds?

[Jörg Wartenberg (joerg-ubuntu)]

I just tried with latest Main build on Windows7. I can confirm this behavior for all "(GL ES)" waveform types, while the others work flawless.

[Be (be.ing)]

GL ES? Do you mean GLSL? Do the plain GL waveforms work okay?

[Jörg Wartenberg (joerg-ubuntu)]

In the "Waveform type" combobox, there are only waveforms with suffix (GL SL) and without any suffix. The waveform types without suffix always work for me - but I'm not the original reporter of this bug.

Can anybody else confirm this?

Define a Windows environment variable "QT_OPENGL" and set it to "desktop" solved the problem for me

rafaelfrench, what GPU do you have? Are the drivers up to date? Can you please test opening a command prompt and run:

set QT_OPENGL=desktop

then

C:\Program Files\Mixxx\Mixxx.exe
