It happens if you return the color settings to default, it happens if you take the colors from the physical stackup. The physical stackup has no entry to enter the opacity of the soldermask. The solution would be simple to set the soldermask opacity to 83% by default as is the case for all default colors and not to 100% as it is now. I think by default it should load the colors from the PCB stackup and if it doesn't find them it should switch to local settings.  # KiCad Version <!-- Copy version information (from main menu Help->About KiCad ->Copy Version Info) and paste it between the triple backticks below to preserve the formatting. --> ``` Application: KiCad Version: 5.99.0-unknown-r20149-23f7ba6e, debug build Libraries: wxWidgets 3.0.5 libcurl/7.69.1 OpenSSL/1.1.1g-fips zlib/1.2.11 brotli/1.0.7 libidn2/2.3.0 libpsl/0.21.0 (+libidn2/2.3.0) libssh/0.9.5/openssl/zlib nghttp2/1.41.0 Platform: Linux 5.8.9-200.fc32.x86_64 x86_64, 64 bit, Little endian, wxGTK Build Info: Date: Sep 19 2020 11:05:42 wxWidgets: 3.0.4 (wchar_t,wx containers,compatible with 2.8) GTK+ 3.24 Boost: 1.69.0 OCC: 7.4.0 Curl: 7.69.1 ngspice: 32 Compiler: GCC 10.2.1 with C++ ABI 1014 Build settings: KICAD_SCRIPTING=ON KICAD_SCRIPTING_MODULES=ON KICAD_SCRIPTING_PYTHON3=ON KICAD_SCRIPTING_WXPYTHON=ON KICAD_SCRIPTING_WXPYTHON_PHOENIX=ON KICAD_SCRIPTING_ACTION_MENU=ON BUILD_GITHUB_PLUGIN=ON KICAD_USE_OCC=ON KICAD_SPICE=ON KICAD_STDLIB_DEBUG=OFF KICAD_STDLIB_LIGHT_DEBUG=OFF KICAD_SANITIZE=OFF ```
