https://bugs.winehq.org/show_bug.cgi?id=39921 YAL <yal(a)csoftcom.com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |yal(a)csoftcom.com --- Comment #8 from YAL <yal(a)csoftcom.com> --- As nanoCAD developer I've investigated this issue and here is conclusion: Long time ago WINE has a kind of bug in MaskBlt. I've made workaround under sort of "is_WINE" dynamic condition flag, that still persist in nanoCAD5 code (it's bad, I know, but we need to satisfy users at that time). MaskBlt already fixed in WINE and it works now exactly like in Windows, but my workaround caused now such drawing effect. I've built patched version of nanoCAD5 dll, so you can test it (zip attached). -- Do not reply to this email, post in Bugzilla using the above URL to reply.
