Description
Checklist
- I have read the appropriate section in the contributing guidelines
- I believe this issue is a problem with polybar itself and not a misconfiguration on my part
- I have searched for other open and closed issues that may have already reported this problem
- I have checked the known issues page for this problem.
- I have followed the debugging guide to narrow down the problem to a minimal config.
Steps to reproduce
polybar -l trace -c xwindow.ini
Minimal config
