First off, please bear with me if I make some noobish mistakes. I just recently
switched to Linux, and this is my first actual report I've made on a bug. This
is also my first venture into the depths of the actual GPU hardware.

I have a Radeon HD3650 (RV635, non-mobility) card, and I can verify that the
shadow stripes are still present. I don't play HoN, but I am playing the new S2
game, Strife, which uses the same engine. Setting shadows to lowest possible
does accomplish the same as Off in HoN as mentioned above.

I'd like to point out that the stripes actually change in size depending on the
variability of the setting. Medium shadows have about a 50/50 split of the dark
stripe compared to the light stripe. High has mostly full shadows with a very
little bit on the lighter stripe.

One last thing, and probably unrelated, but my card also seems to have problems
with some transparent shaders, as well. In Strife, it's visible in the launcher
quite easily.

This is with Shaders on Low. Higher settings result in worse corruption for
this. The blue and green boxes seem to change depending on which part they're
in. Green for the lightshaft/fog that runs across the center, as well as the
gem glow in the top-left. Cyan/blue for the background lighting.

For the record, both of these problems render fine in software mode.

I'm using Xubuntu 14.04, with the obiaf ppa, if it helps, though I can say this
issue is present in every version I've tried, including the default drivers on
the original 14.04 disc, as well as some of the stuff I managed to get working
from 13.10. Therefore, I can assume they're both not regressions, but just
missing or otherwise not-fully-working implementations.
