Subject: [PATCH 4/6] composite: Fix COW creation for Xinerama
|
|
|
|
Say you have two 800x600 screens left/right of each other. A window
|
|
that's 200x200 at +700+0 in protocol coordinate space will appear to be
|
|
at -100+0 in the coordinate space of the right hand screen. Put another
|
|
way: windows are in the coordinate space of their root window pixmap.
|
|
|
|
We weren't doing this translation for the COW, so when rendering came in
|
|
to it you'd see the top-left chunk of the COW on all screens. Cool
|
|
effect and all, but wrong.
