when using gallium nine, A Hat in Time locks up the entire system (requires a hard reboot) on certain scenes. I'm running a r9 270x with the amdgpu driver and mesa-git 110950.fc455797c1b-1 + llvm-svn 360675-1 this issue was discussed with the gallium nine guys here: https://github.com/iXit/wine-nine-standalone/issues/35 and they narrowed it down to radeonsi using AMD_DEBUG=mono fixes the issue this is the apitrace for gallium nine https://mega.nz/#!ZJhRhYaR!cVsMkRYkl6kPl0f43sMKu8NI4pvA4eE85cbLJyoQ-jE the hang happens on the very last part of the trace, when the green goo in the middle of the room is on screen. the area is chapter3, act6 and all other challenges that take place there playing back the trace also causes the same hang. playing back the trace with AMD_DEBUG=mono works correctly without any hangs other users report that turning off dynamic lights also fixes the issue another user reported a similar hang in chapter 1, act 4 with this apitrace https://kiwii.casa/downloads/d3d9.trace.xz
I'd like to add, besides the R9 270X, this also affects Vega (both traces hang my Vega 64) and Polaris (one user reports the chapter 1, act 4 hang to be 100% reproducible on his RX 580). I can also confirm both traces to play fine on my card with AMD_DEBUG=mono on mesa-git and R600_DEBUG=mono on mesa 19.0.4. With the NIR backend (R600_DEBUG=nir) it still hangs the same way as with default TGSI on both 19.0.4 and git. Note: Both traces are recorded on x64 and may need to be replayed with x64 apitrace to prevent running out of memory during shader compilation.
