The scrollbar gripper parts of the Win8RTM theme use a 32bit bitmap, which makes uxtheme think it has an alpha channel but doesn't, specifically, uxtheme/msstyles.c prepare_alpha() should return FALSE has_alpha value. Further investigation is needed because XP seems to handle such bitmaps well. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
