Describe the issue

The trees in the background are heavily whitish flickering with LLVM Screenshot_20200411_220012

This is not happening with PRO 19.30 Screenshot_20200411_215759

ACO is completely freaking out, showing distorted polygons. Screenshot_20200411_211025

Renderdoc capture - big file over 800Mb compressed.wine64-preloader_2020.04.11_21.14_frame25027.rdc.xz

ACO Renderdoc capture gives me a Segmentation fault. Still worth uploading it? Also it seems there is VK_EXT_shader_demote_to_helper_invocation used with ACO - I would try to start without to see if it fixes the game, but how? MESA_EXTENSION_OVERRIDE=-VK_EXT_shader_demote_to_helper_invocation seems not to help here.
