Seems like it was because I was using xrender. Since xrender was removed as an
option in Plasma 5.23 I don't think this issue will happen again.

I can confirm that this issue persists for me, regardless of which compositing
method I use. Here's what I see: https://i.imgur.com/xXON5lP.gif

There's something terribly odd here.

The alpha channel actually works "somehow", but it seems it's interleaved with
the color channels.
Blue, red or black show a reasonable alpha, but even a mid gray (160,160,160)
with a supposed alpha of 16 is rather opaque (maybe 160?) - and white!

Converting the image to QImage::Format_ARGB32_Premultiplied or
QImage::Format_RGBA (it's QImage::Format_ARGB32 and I explicitly painted
the content to avoid loading issues) has no impact.

static xcb_render_picture_t createPicture(xcb_pixmap_t pix, int depth)
always takes a depth of 32 and returns the same format (regardless of the image
color)

On top of that, it looks somewhat related to the composition - yellow on black
seems far more opaque than yellow on white, XCB_RENDER_PICT_OP_ATOP instead of
XCB_RENDER_PICT_OP_OVER doesn't change that.

Means it's likely been broken all KF5

Nope.

I never looked at these settings before, (compositor), so they would have been
set at the default settings.  I know that this used to work fine until about
two weeks ago.  After a system update (I think it was one of the Xorg updates)
it broke.  When no patches came, I submitted this report.

My installation is about one month old.

Not sure if it is relevant, but I've got Deepin installed as an alternative DE
- would this have broken something?

OK - so switched Compositor to OpenGL 3.1 and the problem is resolved.  Not
sure why or how it got set to xRender.

Nope, Broadwell/SNA - not a driver issue.

> This used to work correctly
Can you provide more information about this?
Notably whether this may have "broken" due to the (deliberate?) switch from GL
to XRender?
Can you confirm it ever worked on the XRender backend in the KF5 based KWin?

When viewing tm_inner.png and tm_outer.png with gwenview they both appear to be
correct  (partial circles on transparent background).
