更关键的是稳定性。集成式Agent依赖协议交互，输入输出结构清晰，可控性强；OpenClaw则高度依赖模型对像素界面的理解。一旦出现动态弹窗、页面刷新或UI微调，就可能产生“视觉幻觉”，导致点击偏移甚至陷入循环错误。

While this really depends on the individual, there can be anything from a mild adjustment period to some more serious confusion. Personally, I find the transitional period between any keyboard with a somewhat-standard QWERTY layout to be fairly quick, since all of the keys are in positions at least somewhat-close to what I expect. However, even I struggle with more “strange” layouts like those found on ortholinear keyboards. After years of typing on standard keyboards, the familiar naturally becomes more familiar, and the unfamiliar can feel truly alien. However, if you are genuinely passionate about a new layout, I’ve often found that the transitional period is well worth the end result of using something that you really enjoy. It might suck for a bit, but don’t let that stop you!

Uniform regions (solid backgrounds, smooth gradients) get stored as large blocks. Detailed regions (edges, textures) get subdivided into smaller blocks. You end up with a compressed representation that preserves detail where it exists and simplifies where it can.
