TW kconfig Screensaver - OpenGL screen savers broken, Preview shown out of dialog??

Yasuhiko, Checking in kconfig screensavers, all of the OpenGL screen savers are broken and no longer work. For all of the other screensavers, the Preview that should be shown at the right side of the dialog are now shown up under the titlebar somewhere. You can see a few pixels of the preview under the titlebar on the right site. No telling what is the cause. If you have time, can you confirm this behavior? -- David C. Rankin, J.D.,P.E.
