# Objective Looks like #15489 broke some examples :) And there are some other issues as well. Gabe's brother Gabe is tiny in the `sprite_animation` example:  Gabe is not running in the `sprite_picking` example, and (unrelated) is also very blurry: (note that the screenshot is a bit zoomed in)  Unrelated to sprites, the text in the `simple_picking` example is way too dark when hovered:  ## Solution Both Gabes are now the correct size:  Gabe is crisp and running:  The text has better contrast:
