I'm not sure where minor bug reports for the IDE should be reported - this doesn't seem to be worth opening a ticket for.
In MCUX v11.6.1 when dark mode is enabled, the console view renders compiler warnings in white-on-white text. Also, the entire view starts out white until it gets focus for the first time.
This is just a nuisance since you can still read the text by selecting it, but it seems like it should be a quick fix.
