When I enable it in the Startup Applications, tilda always spawns ignoring the transparency settings and in full opaque mode. I have to quit it and start it again so that transparency returns, or just disable it from the Startup Applications and start it manually on every boot.
I have not found a fix for this, bug reports goes way back to 2010 on it. A possible work-a-round here.

This has been fixed in m16.10
I am using this script as workaround, which simply delays the start of Tilda by a couple of seconds.
#!/bin/sh sleep 8s /usr/lib/ubuntu-mate/ubuntu-mate-tilda
Yes, I have found that putting various delays in many startup programs, in order to spread out their loading during bootup/login, fixes many issues such as this.
Thank you all. Got a clear explanation of the problem from that bug report and a non-intrusive workaround to fix the problem.
