Re: [Gimp-user] Rotating Layers

[Daniel Hauck <daniel yacg com>]

I have confirmed your symptoms and also figured out how to resolve your 
problem.
When doing the "rotate tool" (I presume that's how you are rotating) 
there is a setting within that tool's configuration which enables the 
"Show image preview" and directly below that is a setting for "Image 
opacity."  You can either disable the preview or leave it enabled and 
reduce the opacity at that time.
Why having a layer which is already set to less than 100% opacity 
switches to 100% opacity while the rotation is going on escapes me, but 
the effect is harmless.  But perhaps it is because the opacity setting 
on a layer is an effect like masking which is kind of like meta data for 
the main graphical data.  The rotate tool probably doesn't want to deal 
with both the later and its extra data at the same time.
