Linux

Fonts showing up as rectangles

The following command should help:

rm -rf ~/.cache/fontconfig
rm -rf ~/snap/codium/common/.cache
fc-cache -r

Global menu workaround for KDE

Install these packages on Fedora:

• libdbusmenu-devel
• dbus-glib-devel
• libdbusmenu

On Ubuntu this package is called libdbusmenu-glib4.

Flatpak most common issues

• blurry screen with HiDPI on wayland run:

  flatpak override --user --nosocket=wayland com.vscodium.codium
  

• To execute commands on the host system, run inside the sandbox

  flatpak-spawn --host <COMMAND>
  # or
  host-spawn <COMMAND>
  

• Where is my X extension? AKA modify product.json TL;DR: use https://open-vsx.org/extension/zokugun/vsix-manager

• SDKs see this

• If you have any other problems with the flatpak package try to look on the FAQ maybe the solution is already there or open an issue.

macOS

Since the App is signed with a self-signed certificate, on the first launch, you might see the following messages:

App can't be opened because Apple cannot check it for malicious software

You can right-click the App and choose Open.

"VSCodium.app" is damaged and can’t be opened. You should move it to the Bin.

The following command will remove the quarantine attribute.

xattr -r -d com.apple.quarantine /Applications/VSCodium.app
