Regarding the issue of obtaining miou at a resolution of 64 × 2048

Hello! I can get normal results using your code at both 64 × 512 and 64 × 1024 resolutions. But why does the same code result in poor accuracy at a resolution of 64 × 2048, even lower than the accuracy at 64 × 1024. Very strange, looking forward to your reply.
