Configuration file

``` active-opacity = 1.000000; backend = "glx"; daemon = true; fade-delta = 10; fade-exclude = [ ]; fade-in-step = 0.028000; fade-out-step = 0.030000; fading = false; inactive-opacity = 1.000000; opacity-rule = [ ]; shadow = false; shadow-exclude = [ ]; shadow-offset-x = -15; shadow-offset-y = -15; shadow-opacity = 0.750000; vsync = false; wintypes: { dropdown_menu = { opacity = 1.000000; }; popup_menu = { opacity = 1.000000; }; }; ```

Current Behavior

Many, many messages like the following:

Aug 28 21:55:03 msa1 xserver-wrapper[313038]: (WW) AMDGPU(0): flip queue failed: Invalid argument
Aug 28 21:55:03 msa1 xserver-wrapper[313038]: (WW) AMDGPU(0): Page flip failed: Invalid argument
Aug 28 21:55:03 msa1 xserver-wrapper[313038]: (EE) AMDGPU(0): present flip failed

Always in this group of 3.

Otherwise, no abnormal behavior as far as I can see. Visually there's no difference between xrender backend (which doesn't cause this error) and glx/egl. However, xsecurelock doesn't work well with the xrender backend, so I was hoping to use the glx backend...it just spams my system log an annoying amount.
