Hi All, I'm trying to solve an issue in Wine where child windows that use opengl are not being clipped or positioned correctly. The problem is caused by the fact that in Wine we only use a X window for top level windows and all child Windows are "light weight" windows managed by Wine with no corresponding X window.
Part of the current solution is to override the viewport and scissor to correctly place and clip the child window on the top level X window. This works fine until an application calls glXSwapBuffers. My NVidia proprietary driver does honor the viewport and scissor on a glXSwapBuffer so all is good but if I switch to Mesa it doesn't so everything outside the viewport/scissor gets clobbered. The glX spec. doesn't specify how glXSwapBuffers should handle the viewport or scissor. My question is why don't the Mesa drivers honor the viewport or scissor? Was it a conscious decision? Is it difficult to do? Any input would be appreciated. Thanks, /Ulrich ------------------------------------------------------------------------- Take Surveys. Earn Cash.
