I'm completely at loss now. I'm debugging very complex application which actually consists of several simultaneously running processes. Perhaps interaction between processes leads to some unexpected behaviour. Also I don't understand why winedbg prints dc->xformWorld2Vport.eM11 = 0.0, though dc->xformWorld2Vport.eM11 is always 1.0 in the log trace (added to X11DRV_PEN_SelectObject right before the GDI_ROUND call). Something wrong, but I don't know how proceed further yet. Any thoughts?
