Linux

Fonts showing up as rectangles

The following command should help:

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

Text and/or the entire interface not appearing

You have likely encountered a bug in Chromium and Electron when compiling Mesa shaders, which has affected all Visual Studio Code and VSCodium versions for Linux distributions since 1.82. The current workaround (see microsoft/vscode#190437) is to delete the GPU cache as follows:

rm -rf ~/.config/VSCodium/GPUCache

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.

Remote SSH doesn't work

Use the VSCodium's compatible extension Open Remote - SSH.

On the server, in the sshd config, AllowTcpForwarding need to be set to yes.

It might requires additional dependencies due to the OS/distro (alpine).
