# Flatpak Information

Below is the information we deem essential for users to know about Flatpak runtimes.

Because of Flatpak’s design, most applications automatically install a runtime that includes graphics libraries such as MESA or, for NVIDIA hardware, NVIDIA driver runtimes; therefore, Flatpak applications do not use system libraries.

- For the NVIDIA driver runtimes Flatpak installs, they must match the driver version installed on the system. Not installing other NVIDIA driver runtimes will prevent applications that require 3D acceleration from working.
- Flatpak does not automatically remove older NVIDIA driver runtime versions.
- We recommend rebooting after upgrading the MESA or NVIDIA driver runtimes, as we’ve observed that applications requiring 3D acceleration won’t work; logging out and back in isn’t enough.

App developers must update Flatpak applications like MangoHud to use the newer runtimes before they can work again. Flatpak, like other package managers, uses a dependency-based design. When an application updates and the new version requires an updated base runtime or SDK, Flatpak doesn’t automatically install the required versions alongside the application, so users must install them manually.
