It works with some drivers but not with Mesa. It doesn't seem to be a way to fix it in Wine in a non-hacky way. There is Mesa compat option for the issue concerned by this bug (allow_glsl_120_subset_in_110) which is already enabled for some games and can be enabled for Cossacks 3 by adding the following into /usr/share/drirc.d/00-mesa-defaults.conf into driconf/device section: <application name="Cossacks 3" executable="cossacks.exe"> <option name="allow_glsl_120_subset_in_110" value="true" /> </application> Instead of editing system wide dri.conf file it can be copied to $HOME/.drirc (that is a file, not directory) and edited there, that file takes precedence. I suppose this can in principle be suggested as an option in Mesa's default dri.conf file to Mesa. I made a hack in Proton fixing it on the way of another issue with Cossacks 3: https://github.com/ValveSoftware/wine/commit/4985f64197c10cbc74d2bb305190c16... That hack is fixing disappearing units issue on AMD (I could not find a Winehq bug for that) in the first place for which I didn't find a better way around rather than fixing up the shaders, so added '#version 120' there too on the way. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
