 * `xr_glx_hybrid` backend renders the updated screen contents with X Render and presents it on the screen with GLX. It attempts to address the rendering issues some users encountered with GLX backend and enables the better VSync of GLX backends. *--vsync-use-glfinish* might fix some rendering issues with this backend.

-*--glx-no-stencil*::
-  GLX backend: Avoid using stencil buffer, useful if you don't have a stencil buffer. Might cause incorrect opacity when rendering transparent content (but never practically happened) and may not work with *--blur-background*. My tests show a 15% performance boost. Recommended.
-
-*--glx-no-rebind-pixmap*::
-	GLX backend: Avoid rebinding pixmap on window damage. Probably could improve performance on rapid window content changes, but is known to break things on some drivers (LLVMpipe, xf86-video-intel, etc.). Recommended if it works.
-
 *--no-use-damage*::
 	Disable the use of damage information. This cause the whole screen to be redrawn every time, instead of the part of the screen has actually changed. Potentially degrades the performance, but might fix some artifacts.
