Hello


The drivers we ship are exactly the same as the ones from AMD , but 
differently packaged ( in a way which takes advantage of the stable ABI 
of the kernel, thus not requiring reinstalling after each kernel upgrade 
). We ship the version you mentioned but also the newer one ( 15.12 
<https://support.amd.com/en-us/download/desktop?os=Linux+x86_64>). Once 
CentOS 7.3 is out I will also try to package 16.10 
<https://support.amd.com/en-us/kb-articles/Pages/AMD-Radeon-GPU-PRO-Linux-Beta-Driver%E2%80%93Release-Notes.aspx>

As of your issue: the message about missing UMS support is not 
important, AFAIK.  If everything  is OK you should get in the Xorg.log 
something similar to:

[  69.734] (II) Loading /usr/lib64/xorg/modules/extensions/fglrx/libglx.so
[    69.761] (II) LoadModule: "fglrx"
[    69.778] (II) Loading /usr/lib64/xorg/modules/drivers/fglrx_drv.so

[    70.001] (II) Module fglrxdrm: vendor="FireGL - AMD Technologies Inc."
followed by a whole bunch of lines prefixed with fglrx:

[    71.848] (**) fglrx(0): NoAccel = NO
[    71.848] (**) fglrx(0): AMD 2D Acceleration Architecture enabled

[    71.868] (II) fglrx(0): Primary V_BIOS segment is: 0xc000
and many many more

     If only kodi is the application that triggers bad effects, you 
should look into tweaking it, I know that it likes to have direct access 
to hardware. You could even run it directly, by using 
http://kodi.wiki/view/OpenELEC.
