--- Comment #16 from Dmitry Timoshkov dmitry@baikal.ru --- Created attachment 50175 --> https://bugs.winehq.org/attachment.cgi?id=50175 patch
Attached patch should move the burden of supporting the GIF encoding from gdiplus to the real offender - windowscodecs, and make the task of detecting the problem slightly more easier to recognize from wine console FIXME spam.
Moreover, most of affected applications should start work until they actually attempt to create a GIF encoded stream or file, but that's a separate problem.
