Why does the radical for water and ice often look so weird
As others have commented, it is just another font. I would say just ignore it and as a learner, stick to the standard one for now, which is like three short strokes on the left. It would make more sense if we look into the origin of water character in Chinese: 水 (shui3). The pictographic form for 水 (shui3) looks like a river flow, which gradually evolved into the three strokes as the radical form for water character in Chinese: 水 (shui3).
