Copy and paste output corrupting on OSX 10.9

[Arthur User]

When copy and pasting between inkscape windows, random objects have what looks like a large chequerbooard semi opaque overlay regardless of pasteboard/clip board settings.

Please provide information about OS/platform and Inkscape version (see Inkscape menu 'Help > About Inkscape') with each report you file, thx.

To allow further investigation of the reported issue, please attach two sample files: the document with the original object, and a copy saved after the reported issue has occurred.

I believe the effect I was seeing was colour jitter some how being applied to layers in objects - again I've been unable to reproduce then same effect but this was one of a series of issues I was having to deal with simultaneously whilst working to a deadline so I wasn't solely concentrating on the steps I'd taken to get this to occur.

> the effect I was seeing was colour jitter (…)

Possibly the original layer had a blend mode applied, and when copying objects to another layer or document, the layer blend mode inherited by the copy&pasted object may result in rendering artifacts (especially if the target layer at some point also uses a blend mode).

The unexpected inheritance of layer styles is tracked in bug #233800; rendering artifacts with feBlend in bug #502170. Without an example or steps to reproduce, there is however no way to verify what the original problem was.

Based on the reporter's feedback, proposing to close this report. It can be reopened any time later in case more information can be provided by the reporter, e.g. if the problem reoccurs in a new drawing.

Closing due to lack of a suitable test case which would allow further investigation of the reported problem.

Please feel free to reopen the report in case it re-occurs with latest stable Inkscape 0.91, and attach a test case (SVG files, ideally two versions: one saved before (or a backup), and one after the described effect was observed.)
