Obviously, this conclusion was a mistake. I found the bug related to my problem and a workaround [1]. This problem will be present in all nvidia304 users. [1] kwin_x11 does not paint windows, uses 100% CPU in OpenGL mode, under NVidia Legacy driver 304, GeForce 7025 / nForce 630a https://bugs.kde.org/show_bug.cgi?id=343773
