Hello! Yeah this may be a multi-monitor issue. You can try clearing Pixelorama's settings to see if that fixes the issue for you. You can do that by deleting the "config.ini" file found in C:\Users\[USERNAME]\AppData\Roaming\Pixelorama\ if you are on Windows, ~/.local/share/Pixelorama/ if you are on Linux, or /Users/[USERNAME]/Library/Application Support/Pixelorama/ if you are on macOS.
