I also have this issue after pausing and resuming a track:

I'm seeing this as well. It appears that this has occurred due to an upgrade in the version of tui-rs from version 0.14.0 -> 0.16.0 (1ef37e7). I just tested downgrading back to 0.14.0 and the text is properly inverted when overtaken by the gauge bar.

I think we ought to open an issue in tui-rs about this (if one does not already exist) and then maybe roll back the version until it gets fixed, unless we need 0.16.0 for some feature.

I opened an issue on the tui-rs repo (fdehau/tui-rs#538) describing the regression.

As a stop gap measure for spotify-tui, instead of reverting to an earlier version of tui-rs, we can simply ignore the user's configured progress bar label color until this regression gets fixed. Essentially, we can change src/ui/mod.rs:1052 from

Style::default().fg(app.user_config.theme.playbar_progress_text),

to be

Style::default(), // .fg(app.user_config.theme.playbar_progress_text),  --- To be added back in when fdehau/tui-rs#538 is resolved 

instead. This will make the label default to the progress bar foreground color and it will be properly inverted when the progress overtakes the label.
