Hero screen stays darkened after crafting and equipping items a little too fast

This bug is rather minor compared to the startup lag I posted earlier: the screen where you see the Hero do their little animation continues to stay dark after crafting items. It occurs for me whenever I do a “craft-all” for a Hero or simply craft and equip items faster than I should.

This wouldn’t be a problem if it disappeared after leaving the affected Hero screen. However it persists indefinitely until I enter a match or I completely exit the game.

Anyone else getting this bug?

Edit, screen caps:
