[Bug] Terminal UI Flickering and Inconsistent Code Generation Behavior

Bug Description
the window keeps refreshing with history and keeps flickering, hard to read unless I type / in the console. Also, when I specifically ask it to design, it always generates complete code, not a sketch but complete code. When I ask it to generate complete code, misses tests, code isn't complete without tests
