Note: only happens when wezterm window is active (has the focus)

Note that wezterm record only records escape sequences from inside a terminal session. Replaying that recording here doesn't reproduce any flashing. You didn't include any logs in your report. Please check to see if something is being shown there. Please also share those logs: they help me understand the machine configuration better.

Are there certain actions that you are taking that trigger this behavior? Does it reproduce when you run wezterm -n with no configuration?

Sorry for the delayed response... it did not happen again until today.. seems to be associated with starting Neovim although it continues after quitting Neovim and even after restarting wezterm. It only happens when wezterm has the focus as you see in the movie. Thanks again for all the good work you do on this app.
