ptrckw,
Thank you for answering our questions.
You mentioned that you have Dark Mode enabled; does the issue also happen when using Light Mode? More about how to manage the Dark Mode and Light Mode settings here: Use Dark Mode on your iPhone, iPad, or iPod touch
Since noticing this behavior, has your device been restarted using these steps? Restart your iPhone If so, does the issue seem to resolve temporarily after restarting, or is there no change?
Are any display accommodations enabled on the device? This page outlines how to view and manage the display accommodations: Use display and text size preferences on your iPhone, iPad, and iPod touch
Thank you!
