[Bug]: Image download progress bar breaks rebuilds. #883
Description
I have done the following
- I have searched the existing issues
- If possible, I've reproduced the issue using the 'main' branch of this project
Steps to reproduce
Build an image with a simple Dockerfile (FROM docker.io/library/alpine:latest should reproduce it).
Perform the same build command.
Current behavior
% container build -t test -f Dockerfile .
Warning! Running debug build. Performance may be degraded.
