To recreate behaviour:
- Run Wezterm
- Press Ctrl + -
- Observe behaviour
Due to the nature of the problem its not possible for me to capture a screenshot on my current system as opening the screenshot utility results in a new window opening after which I have to switch back to Wezterm, and switching from Wezterm to something/anything else resolves the problem. Even invocation of window switching when its the only window open causes the window to re-size and fill the screenspace correctly once again.
