iterm2 first tab transparency differs from default
In my case this was due to HotKey windows was created after pressing hotkey, but after CMD+T new tab was created with Default profile. So you can either set HotKey as default or rework your shortcuts. You can experience with this by clicking right mouse button -&gt; New Window/New Tab and then Default /HotKey Window profile. After you will define what you would expect here it should be easier to configure
