Fix a 'round title bar corner background should be transparent not black' problem when first painted. OK if resized etc..so just on first paint. Before fix http://www.straightrunning.com/images/round1.png After fix http://www.straightrunning.com/images/round2.png The attached patch, in WM_CREATE, forces the shaped region invalid and so it gets painted correctly when WM_PAINT is first entered.
Created attachment 5990 [details] [review] Patch to fix problem
P.S. applicable in 'multiwindow' mode only and has been a bug in Cygwin/X and Xming for ages!
Applied. Thanks.
