I replaced gles with glew and tried setting different backends, but the other renderers (e.g. software) are unrecognized and it seems to fall back to FemtoVG, which crashes. Is this a known issue on Windows? Or am I missing some config or build flag? I just want to play a 3D animation in a Slint-based app. Any advice or working setups would be appreciated!
\nThanks in advance

Hi! I'm trying to run the opengl_texture example from the Slint repo on Windows, using C++ and GLEW, but I'm having trouble getting any output — the window stays blank and exits in a second., even though the app gets build with no problem. The message I get is: I replaced gles with glew and tried setting different backends, but the other renderers (e.g. software) are unrecognized and it seems to fall back to FemtoVG, which crashes. Is this a known issue on Windows? Or am I missing some config or build flag? I just want to play a 3D animation in a Slint-based app. Any advice or working setups would be appreciated! Thanks in advance |

Ok, I've found it. The issue is that with C++ we accidentally enabled the WGPU renderer by default, which doesn't use OpenGL. With Rust the backend selector prevents this from becoming a choice, but we've also got our defaults wrong. I'll fix that. Meanwhile, there are two different ways how you can solve this:
