This might be fixed by the experimental workaround in https://gitorious.org/mypaint/mypaint/commit/f38b4b8a52e7f679853992424b8d5cd985efec9c. I'm not able to reproduce this right now on my system (native Debian testing/Wheezy, under Gnome3 or Xfce4; Virtualbox guest Ubuntu 12.10 under Unity) with Intel video hardware, but it seems plausible .

Please could everyone test against the latest git and report back here or on bug #20311? If you're bitten by this bug, hopefully you'll find that picking still doesn't work on non-MyPaint windows, but that it's fixed on MyPaint's own canvases, toolbars and buttons.

Would be interested if you see the colour picker pick pure #ff0000 red anywhere it shouldn't. I've improved the error checking, and I'm using that colour as a flag for when grabbing areas of the screen to a pixbuf before sampling/averaging fails in a detectable way. It won't be enough to fix this everywhere, but it should allow us to distinguish between fail cases.

Bug #17076 is a duplicate of this (and confirms it: same OS, same issue). Probably it is an upstream issue, but perhaps we can be smarter about what we do with picking too, to make GTK bugs around colour picking less painful to users. Would be nice if it at least worked on the canvas...

Grubert, I can't find this issue in gtk bugreport.

If this a GTK+ issue, would you mind to report it in the bugtracker? there is already a bug about color picker in win32 so it may be a good chance this bug may get fixed too. Thanks

The color picker doesn't pick color ( only black ) on a secondary screen.
This problem is here since version O.9

And, with the same machine under Linux, the problem is no more...
