<pre>We recently setup Dolphin's automated rendering tests on Fiji XT with
Mesa/amdgpu. It started detected a random rendering issue which I think we can
attribute to a driver bug.
See <a href="https://fifoci.dolphin-emu.org/compare/1086020-1085934/">https://fifoci.dolphin-emu.org/compare/1086020-1085934/</a> . Left side has the
"bad" rendering, right side the "good" rendering.
The issue is properly captured in this apitrace:
<a href="http://delroth.net/radeon-unpredictable.trace">http://delroth.net/radeon-unpredictable.trace</a> -- rendering it on my Fiji XT
system shows the lines but rendering it on i965 doesn't.
We have also had reports of users seeing this in action on Pitcairn GPUs:
