BUT... it cant sync the canvases in the borders, or the menus, or the background or the popups. these are separate windows and canvases. literally e is doing x(shm)getimage() the pixels from x11 when updates happen. since async rendering may be rendering a NEW frame WHILE it is doing a getimage for the old one (the border canvas is rendering async to the comp canvas in its own thread), this will be a source of issues. before because evas_render was synchronous, this serialized rendering ensuring it was done in a popup/border etc. BEFORE comp grabbed the pixels and rendered the comp canvas. NOW.. this other rendering may still be underway in parallel. -- ------------- Codito, ergo sum - "I code, therefore I am" -------------- The Rasterman (Carsten Haitzler) ras...@rasterman.com ------------------------------------------------------------------------------ Master HTML5, CSS3, ASP.NET, MVC, AJAX, Knockout.js, Web API and much more.
