Subject: [PATCH] gl-renderer: Fix debug clear region
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The debug clear region must be generated out of the current render
buffer's damage region, not out of the current damage region, unless
shadow 16F is enabled.
