I tested on a fresh Ubuntu 18.04 virtual machine, with Pinta installed from https://launchpad.net/~pinta-maintainers/+archive/ubuntu/pinta-stable, and the brightness / contrast effects updated correctly. I'm not sure what might be different in your setup - are you using the snap or flatpak packages of Pinta?
