Bug is at least reproducable other user on reddit has confirmed https://www.reddit.com/r/wine_gaming/comments/ckhwhp/overwatch_font_rendering_issues_on_5700xt_navi10/evrd5g7?utm_source=share&utm_medium=web2x Moving this to Vulkan / RADV bug Loading the game up under the latest amdvlk from 26/7 renders the fonts correctly (albeit with artefacts that are inherent to that build at the moment on Navi10). It seems I was mistaken under my initial testing, the game fails to render at all under wined3d.

Anyone able to get a renderdoc capture for this? Seems like a Geometry Shader issue with NGG (primitive shaders). You can specify RADV_DEBUG=nongg as a workaround for now. confirming that RADV_DEBUG=nongg workaround fixes the font rendering Should be addressed by https://gitlab.freedesktop.org/mesa/mesa/commit/c037fe5ad1b3556809e5a549306a52a8a8bd1cbf Thanks for the report. |
