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 https://fifoci.dolphin-emu.org/compare/1086020-1085934/ . Left side has the "bad" rendering, right side the "good" rendering. The issue is properly captured in this apitrace: http://delroth.net/radeon-unpredictable.trace -- 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: https://bugs.dolphin-emu.org/issues/9239
