We've made a few improvements to the profile picture area. The text and inactive tabs now have a slightly transparent background, which significantly enhances readability on light profile pictures. The avatar is now 50% larger, which required adjusting the profile picture dimensions as well. Along with this, we updated the default profile picture and optimized the display for different screen sizes. Your profile photo should now be at least 1920px wide and 220px tall. For larger dimensions and on smaller screens, a cropped section of the image will be shown, centered at the top. If the image is smaller than these dimensions, it will simply be stretched.
Feel free to check if your profile picture still looks good after the update and replace it if needed. A quick tip: simple patterns often work better as profile pictures than photos with many subjects and lots of detail, as this helps the text and avatar stand out more clearly.
