Description Nate Graham 2023-06-20 09:46:08 UTC
1. run `plasma-discover --feedback` in Konsole

Discover's main window briefly appears, then disappears in a flash

That doesn't happen

This happened in the past, but was fixed in Plasma 5; see Bug 423493. But it appears to be back in Plasma 6.

Cannot reproduce this, I only get a dump of info in konsole:

Qt WebEngine seems to be initialized from a plugin. Please set Qt::AA_ShareOpenGLContexts using QCoreApplication::setAttribute and QSGRendererInterface::OpenGLRhi using QQuickWindow::setGraphicsApi before constructing QGuiApplication.

Discussed with Nate and he gets it because he has backends. I have a minimal build with no backends, so I don't see the issue.

He mentioned Discover shouldn't load the backends if passing this argument as they aren't neeeded.
