Strictly speaking, the problem has nothing to do with QRhi. What is special with the eglfs' backingstore is that it creates a QRhiTexture and then pulls out the OpenGL texture ID via nativeTexture() right afterwards. In this setup there is nothing that would ensure glTexParameteri is called to override the silly default of OpenGL. Normally this cannot happen because once the QRhiTexture is used for sampling purposes together with a QRhiSampler, all necessary state gets updated. Starting from Qt 6.4, with the QRhi-based backingstore composition changes, the special case where we create QRhiTextures just to get the underlying OpenGL texture got introduced. Ideally the eglfs side should provide its in MIN/MAG filter state, but in the meantime, to be more robust, always set a MIN filter already in QRhiTexture::create(). For most textures this will get changed afterwards.
