On some desktop hardware the ui currently fails to start. This only happens when the _calculate_auto_scale function runs and thereby opens and closes a temporary window. The issue seems to be related to the OpenGLContext getting removed in the raylib close_window function. By directly destroying the glfw window the OpenGLContext does not get removed and the ui is able to start successfully.
seems like a hack to intentionally leave the gl context open when this method finishes
have you explored other fix attempts?
The raylib close_window function doesn't provide a way to leave the context open, it seems like init_window and close_window are designed for an application with a single window that would completely shutdown after closing the window. I don't see any way to create and maintain an opengl context in the raylib api apart from the init_window/close_window commands or dropping into glfw. The only other way I could think of to open and close a window while maintaining the OpenGL Context would be to stop using init_window and instead manage the glfw layer from start to end. Another option would be to find another way to find the dimensions that this function grabs. Overall though, this seems like the most straightforward solution to the issue
