--- Comment #1 from Brennan Kinney <[email protected]> ---
While filing this issue on behalf of another user that raised attention to it,
a related one[1] did reveal itself(it'd be nice if the UI for the search could
also toggle/query closed issues as I didn't notice those were excluded).

I also came across this issue[2] via google results. It showcases videos of
several effects that use transforms with before/after of enabling blur. Scaling
and translation transforms were shown as fine, but ones like Wobbly Windows
were revealed as to why they're not compatible. While I was going through that
and related info to understand the issue, another user shared the same Wobbly
Window effect video directly on reddit[3].

While the reasoning for the closing [1] is clearly explained in [2], I would
like to seek feedback from a developer with knowledge of the issue. Is the
Wobbly Window effect not able to scale the blur texture to fit the bounds of
the Wobbly Window effect and then use the distorted window as an alpha mask
with glStencil or glScissor? I tried to go over the kwin effect code, but I'm
not familiar with the codebase enough(or C++ and OpenGL)  to grok the flow/path
of code for the effects.
