SSAO problem (Radeon 7859 + Catalyst 16.4)

[donizettilorenzo]

With SSAO enabled a black blob forms on glass surfaces (->shader accumulation/integration problem I think) and remains on the screen, moving around.

It SSAO works when "r_useHDR 0" weirdly enough.

[donizettilorenzo]

Yes, but brightness falls down to 0.

[RobertBeckebans]

If it works with r_useHDR 0 then I have an idea how to fix it. I'm going try it this week.

[donizettilorenzo]

Brightness falls down _HOT_switching (in-game) the "r_useHDR" variable.
Restarting the game the brightness is fine.

[RobertBeckebans]

When you change r_useHDR then you have to recompile the GLSL shaders by the command "reloadShaders" in the console.

I have the same issue on NVIDEA K1100M

I'm seeing that too on my Intel HD Graphics 4000 (embedded in an i3-3227U )

rboom3bfg is compiled from trunk git repo, however using system libraries in Debian.

shows errors:
./rbdoom3bfg +set r_useSSAO 1 +set r_useHDR 1
works fine:
./rbdoom3bfg +set r_useSSAO 1 +set r_useHDR 0
./rbdoom3bfg +set r_useSSAO 0 +set r_useHDR 1
./rbdoom3bfg +set r_useSSAO 0 +set r_useHDR 0

(reloadShaders throws plenty of errors)

You said you have an idea how to fix it: Did you come up with some patch which I could test?

reloadShaders fix it for a second, but if I move camera, black blobs and dots appears again

I had a similar problem (screen blacks out after a few seconds of play). Disabling SSAO and HDR fixed it for me. lspci | grep VGA gives me 00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 0b) and I use the RBDOOM-3-BFG-1.1.0.
