--- Comment #10 from Thomas Lübking <thomas.luebk...@gmail.com> --- The X11 server is "unfortunately" pretty much free in deciding when to create expose events (it does so, because it has no data for the window), this could be defeated by a cache (backing store) or bypassing overlay output (not uncommon for GLX) There's afaik no method to get all frontbuffer updates from the server. VNC keeps a copy of the framebuffer and compares the pixels of n with n-1 to know which regions to update. Combining Damage and Un/Map and ConfigureNotify events (alongside a Z test for the latter two) might get you a complete idea on the flattened update region... :-( -- You are receiving this mail because: You are watching all bug changes.
