Distro / Kernel release : Slackware Current (64 bit), 5.9.9
Mono / .NET package version : Mono 6.12.0.90 (Compiled libgdiplus and mono using the SBo slackbuild scripts but updated the versions to 6.0.5 and 6.12.0.90 respectively. IIRC, only removal of a README and changelog, and fix the CD without minor version for the extracted code was needed. Notice that the /etc/mono/* files are not replaced if it is a upgrade and will fail. You need to move the .new over the old versions config)
Graphics driver version : Mesa 20.2.2 in a AMD Rx480 gpu
Works for client, mp server or both : Client
Installation method used : Unpack archive, mono Vintagestory.exe
Hacks : No hacks, the SBo slackbuild already runs cert-sync on install
