GPU hang (ring gfx timeout) with out of bounds UBO read in shader

It hangs in OpenGL game immediately after startup almost always (but sometimes it goes through and works) with dmesg message:
[drm:amdgpu_job_timedout [amdgpu]] ERROR ring gfx timeout, last signaled seq=3324, last emitted seq=3327
I tested it on Radeon RX580, mainline kernel 4.18, Mesa 18.1.3 and Mesa git c0874947.
I could provide game code for testing but I would have to package minimal assets as full game weights pretty much.
