earth tessellation bug
Are you able to do a git bisect to find the commit that caused the issue? No, in the Arch repository there is only the last Mesa-git driver. a rollback to the old version is not possible, and on a stable version of the driver, DXVK does not work. Here are some really quick instructions for building mesa and bisecting the issue. Get and Build RADV: ------------------- git clone https://gitlab.freedesktop.org/mesa/mesa.git cd mesa sudo dnf builddep mesa (this is how you get the mesa build deps on Fedora not sure how you would do that on Arch) sudo mkdir /opt/xorg sudo chown youruserid /opt/xorg ./autogen.sh --prefix=/opt/xorg --with-dri-drivers="" --enable-gles1 --enable-gles2 --enable-shared-glapi --with-gallium-drivers="" --with-vulkan-drivers=radeon --with-egl-platforms=x11,drm --enable-gbm --enable-glx-tls --enable-dri3 make -j4 && make install Use your built version of RADV: ------------------- Add the following to ~/.bashrc and logout and back in (Remember to remove this if you want to switch back to your system version of RADV) # User specific aliases and functions export VK_ICD_FILENAMES=/opt/xorg/share/vulkan/icd.d/radeon_icd.x86_64.json Bisecting the issue: -------------------- Here is a simple intro to git bisect http://webchick.net/node/99 The hardest part will probably be finding a commit that works. From there it should be straight forward. Maybe start with the 18.1 branchpoint 6754c2e83d79f93b3a4c8 (that was the end of april) Good luck. after installing a stable version of this bug disappeared. mesa 18.1.3-1 Really nice, thanks! Closing. (In reply to Samuel Pitoiset from comment #7) > Really nice, thanks! Closing. I don't think that's right. I don't think the bug was even in the 18.1 release to begin with going by the dates given in the initial report. ximik are you able to bisect? Is this still a problem in git? this problem appeared in the git version of the driver in early June. before that I used version 18.0 stable. but DXVK stopped working with it, so I updated to version git. in the middle of May everything was stable. and in late May or early June a bug appeared. Yes, the bug is only in the git version of the driver. *** This bug has been marked as a duplicate of bug 107276 *** |

Created attachment 140505 [details] earth tessellation bug Some surfaces with tessellation are separated from the earth for some distance. The bug is encountered on the map r290x with the latest open mesa-git driver. the bug appeared in early June, in git driver versions at the end of May there was no bug. apitrace can not be done, Far Cry 5 throws an error too long to load.
