*--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-copy-from-front*::
GLX backend: Copy unmodified regions from front buffer instead of redrawing them all. My tests with nvidia-drivers show a 10% decrease in performance when the whole screen is modified, but a 20% increase when only 1/4 is. My tests on nouveau show terrible slowdown. Useful with `--glx-swap-method`, as well.
*--glx-use-copysubbuffermesa*::
GLX backend: Use 'MESA_copy_sub_buffer' to do partial screen update. My tests on nouveau shows a 200% performance boost when only 1/4 of the screen is updated. May break VSync and is not available on some drivers. Overrides *--glx-copy-from-front*.
*--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.
*--glx-swap-method* undefined/exchange/copy/3/4/5/6/buffer-age::
GLX backend: GLX buffer swap method we assume. Could be `undefined` (0), `copy` (1), `exchange` (2), 3-6, or `buffer-age` (-1). `undefined` is the slowest and the safest, and the default value. `copy` is fastest, but may fail on some drivers, 2-6 are gradually slower but safer (6 is still faster than 0). Usually, double buffer means 2, triple buffer means 3. `buffer-age` means auto-detect using 'GLX_EXT_buffer_age', supported by some drivers. Useless with *--glx-use-copysubbuffermesa*. Partially breaks `--resize-damage`. Defaults to `undefined`.

*--glx-use-gpushader4*::
GLX backend: Use 'GL_EXT_gpu_shader4' for some optimization on blur GLSL code. My tests on GTX 670 show no noticeable effect.
