SUMMARY Having a background color but disabled colored numbers causes every piece to be exactly the same. Thus, it's no longer sensibly possible to solve the puzzle, as you don't know which piece is first, second, third etc. STEPS TO REPRODUCE 1. Open fifteen configuration window 2. Enable background color, disable colored numbers 3. Apply OBSERVED RESULT Only way to solve the puzzle is now by pure guessing EXPECTED RESULT The "disable colored numbers" should only be possible to be disabled, if the the widget is using a background image as opposed to a background color.

Git commit 4722d929381121ca19645fa40a0596f483ba4d2b by Christoph Wolk. Committed on 10/08/2025 at 20:47. Pushed by cwo into branch 'master'. applets/fifteenpuzzle: use radio button for label config Fifteen Puzzle allows the user to hide the number labels; this makes the game more challenging (and somewhat more visually appealing) when a background image is used, but virtually unplayable (an almost unwinnable guessing game on reasonable board sizes) with a solid background color. Currently, the settings allow you to go into this essentially broken state. Instead, use a radio button to select label with color or hidden label, and force label display on solid color backgrounds for good measure. When the user switches from image background to solid color, the label radio button is automatically switched if necessary, and the invalid radio button is disabled. And while we're touching this part, do some routine updates to our current best practices, like setting translation contexts and setting text and display properties on icon-only buttons.
