Build: V1.8.4 3850 Mode: Any Mode: Single Player SEED-ID: NA – Applies in all SEEDS MODIFIED PLAYFIELDS: No (no mods, new game) Reproducibility: Always Severity: Minor Type: User interface Summary: Hitbox for closing X in Choose Shape window malfunctioning Description: When you bring up the ‘Choose Shape’ window (where you choose what shape of block to place), the X in the top right corner which should close the window has some kind of issue with its hitbox. Steps to Reproduce: If you approach the X with your mouse from above the X the button highlights (changes to red) and you can click on it. There is a similar, but very small portion of the right side of the X from which you can also get the mouse pointer to activate the button. Approaching the X from the left side or bottom side with your mouse and the button does not highlight and you can’t click on it (no matter where you place your mouse on the X). You have to move your mouse away from the X and approach again, either from the top edge or the small section of the right-hand side which accepts activation. Other info: Tested different resolutions and same section activates in all. NB: I know you can press escape to exit that window.
