For all of Electron's promise in being cross-platform, "I'll just press this button and ship this Electron app on Linux and everything will be fine" is not the current state of things. A lot of it is papercuts like glibc version aggravation, but GPU support is persistently problematic.
The Element app on Linux is currently broken (if you want to use encryption, so basically for everyone) due to an issue with Electron. Luckily it still works in a regular browser. I'm really baffled by how that can happen.
I believe power users or developers can already use this from CLI in Linux. This new app for Windows and MacOS shows this is intended for regular users.
Also is there a link to the source?
