Description

Hello, I use softbuffer to draw my window..
I have this code:


        let mut buffer = surface.buffer_mut().unwrap();
        let pixels = canvas.data();
        for (dst, src) in buffer.iter_mut().zip(pixels.chunks_exact(4)) {
            *dst = (src[0] as u32) << 16 | (src[1] as u32) << 8 | (src[2] as u32);
        }
        if let Err(e) = buffer.present() {
            println!("Error: {:?}", e);
        }

When I send the data pack to X11 server, and screen size is more than 16MB, the program will crash!

it's output like:

Error: PlatformError(Some("Failed to draw image to window"), Some(X11(ConnectionError(MaximumRequestLengthExceeded))))

can you help me to solve it?

Research direction

No source file or test is named. Start by reproducing buffer.present on X11 with a window or screen larger than 16MB, then trace the present path that sends the image to the X11 server. Done means large frames no longer produce MaximumRequestLengthExceeded or crash.
