Ah, I see. It indeed does happen only with solid non-chunked bars. Thanks for clarifying it.

If WindowBlinds-skinned progress bar is partially obscured from the left, it seems that WindowBlinds uses leftmost visible boundary instead of true (obscured) left boundary of progress bar when computing the ratio that must be filled - so visible ratio will distort. This happens if progress bar is partially offscreen or some window above is blocking its partially from the left. Is quite visible, if you take, say, browser download window in process of downloading,
