Created attachment 137985 [details] A video of map dm-curse4 With recent mesa versions some textures in UT2004 are blinking while player moves. You can see this behavior on any map that uses multiple texture layers. I've made a video of DM-Curse4 to show it. I've also tried to record an apitrace, but it fails with segfault. It used to work fine few years ago. Sys spec: Radeon HD7950, Mesa-git e30a165be274e399787ba7d44171567f3d93dcac, llvm 7.0 r327106 64-bit version of UT2004 for linux
I'm not sure if it's specific to radeonsi, i've tested with llvmpipe and got same result.
f314a532fdc7af8381586144d2631d9968331f05 is the first bad commit commit f314a532fdc7af8381586144d2631d9968331f05 Author: Samuel Pitoiset <samuel.pitoiset@gmail.com> Date: Wed Jun 21 11:31:43 2017 +0200 mesa: do not trigger _NEW_TEXTURE_STATE in glActiveTexture() This looks like useless because gl_context::Texture::CurrentUnit is not used by _mesa_update_texture_state() and friends.
