Thread for this report:

After installing today's openSUSE Tumbleweed snapshot (generated on 07-04-2017) and restarting, I found that KWin no longer renders Aurorae themes. Other themes work fine however, and this only seems to affect Aurorae. The problem happens both with and without desktop effects enabled.

The space where the titlebar and border should be is now completely empty, with no graphics or text or buttons showing. However the blur effect is still functional, and clicking and dragging on any window components works correctly (even if they're invisible).
