There is a much cleaner workaround that won't break other apps:
# make a copy of the relevant library
mkdir ~/lib
cp /usr/lib/x86_64-linux-gnu/libxcb.so.1 ~/lib
sed -i 's/BIG-REQUESTS/_IG-REQUESTS/' ~/lib/libxcb.so.1
# set the dynamic loader path to put your library first before executing VS Code
LD_LIBRARY_PATH=$HOME/lib codeObviously, you can tweak your .desktop files and other launchers to set the environment variable solely for VS Code. Go to /usr/share/applications/code.desktop, copy it to ~/.gnome/apps (or wherever your desktop manager likes it) and change the Exec line to read something like:
Exec=sh -c "env LD_LIBRARY_PATH\=\$HOME/lib /usr/share/code/code" %U
