Here a short video illustrating the problem:

reinstalling libcairo 1.10 dockx works without problems

[Matias Särs (msevens)]

This didn't happen with previous versions of cairo?

[telperion (nikita-top)]

No, dockx it has always worked well before,
Now i'm using libcairo2 1.10.2-7, and all is ok.

[Matias Särs (msevens)]

This bug seems to appear only if the dock type is set to "centered" or "corner".

[Matias Särs (msevens)]

Scratch that. It happens with panel type as well. What it does, it seems is to misplace the path by half the width (at horizontal panels at bottom, at least). So everything on the right side of the middle seems to be without a background.

By not using copy_path/append_path the problem (possible cairo bug?) is worked around.
