--- Comment #11 from Huw Davies huw@codeweavers.com 2011-11-21 03:44:13 CST --- I suspect the slow (45ms) cases are because the dib driver has previously forwarded a graphics operation to the winex11 (because it doesn't yet handle that op), so before it can draw the line it needs to copy the bits back from the X11 side. It would be interesting to know which operation is being forwarded. Could you produce a +relay,+tid,+seh,+bitmap,+dib,+x11drv log ?
