Composite render textures with alpha in every backend - #5
Merged
Conversation
All five backends wrapped their Rive render target for the scene graph via createTextureFromRhiTexture without the QQuickWindow::TextureHasAlphaChannel option, so QSGSimpleTextureNode composited the texture as opaque: the renderer's transparent clear (clearColor 0) came out solid black wherever the artboard didn't cover the item. Invisible with Fit.Cover full-bleed artwork — every pixel is painted — which is why it survived this long; any artboard smaller than the item (badges, spot animations over app backgrounds) showed a black box.
