![]() With the extension the program can simply tell the X server "I want to draw these pixels in this colour with this amount of transparency" and the server does the compositing, which is a lot more efficient particularly when several different apps are all trying to write translucent layers that overlap. ![]() Without the extension if a program wants to draw a partially-transparent region on the screen it has to fetch the current contents of that region from the X server, calculate the composite colours for each pixel itself, and then send the resulting composite image back to the X server to be drawn on the screen. The "render extension" is an add-on to the standard X Windows protocol that optimizes various things including the case where apps want to draw pixels with alpha transparency. I also tried using :0 rather than $DISPLAY, but that also failed.Ĭould someone explain briefly (for non-specialists) what "enable_render_extension 0" actually does? It turns off something I imagine, but what exactly? Thank you.
