Hi 👋
I noticed the client log file too large playing on MC 1.19 and there were too many lines with the exact same characters.

The line says:

[Render thread/WARN]: Clearing BufferBuilder with unused batches

And I found that the line comes from net.minecraft.client.render.BufferBuilder#clear().
I think it’s not kind to hardware, so I have written a patch to prevent this warning from being generated.
