--- Comment #6 from Weng Xuetian <wen...@gmail.com> --- Ok, now I discover something new. I tried to downgrade kwin only but problem was still there. But I tried to downgrade whole plasma group, it went back to normal. But once I get breeze updated to 5.5, with either version of kwin the problem appears. So this seems to be related to breeze theme. I tried to use breeze decoration with oxygen widget style, there's no problem, so probably related to breeze widget style.
