How to Reproduce

If I didn't miss any significant detail

install rust 
install llvm x86
clone vcpkg
set LIBCLANG_PATH=C:\Program Files (x86)\LLVM\bin
set PATH=%PATH%;C:\Program Files (x86)\LLVM\bin;%WORKDIR%\vcpkg
set VCPKG_ROOT=%WORKDIR%\vcpkg
rustup default stable-i686-pc-windows-msvc
vcpkg install libvpx:x86-windows-static libyuv:x86-windows-static opus:x86-windows-static
clone rustdesk
cd rustdesk
cargo build
copy %WORKDIR%\sciter-sdk\bin.win\x32\sciter.dll %WORKDIR%\rustdesk\target\debug\sciter.dll
xcopy /E .\target\debug\src\ui .\src\ui
cd target\debug
rustdesk --connect <id>

Expected Behavior

World domination, I guess?

Prebuilt x86 version from Release section works as expected. Some difference in build environment or dependences versions?

Simple as ever. Use nightly rust instead of stable.
rustup override set nightly-i686-pc-windows-msvc

The only thing I regret is that I didn't see (or wouldn't notice) #763 earlier.
