Linux transparency broken unless the GPU is disabled

See electron/electron#28834 and electron/electron#25153

Disabling the GPU will completely break fullscreen visualization.

IMO, until Electron fixes this, visualizations should not work fullscreen on Linux.

Bug introduced when upgrading Electron to 11 (cf. a0dc9e9)

I suggest that you check out this comment left on one of the issues you mentioned: electron/electron#25153 (comment)

I was trying to get vscode transparency working without --disable-gpu and decided to try --use-gl=desktop and to my surprise it worked.

It seems to work for me, which is excellent, seeing that I want to be able to take full advantage of GPU rendering inside transparent framed windows.

Let me know if this does/doesn't work for you — equally, it would be handy if there was no workaround (ie. transparency works out of the box) of course.

(Running Electron 14.0.1 on Debian 10 GNU/Linux with picom compositor and Nvidia drivers)

I tried that option but when I was using the --use-gl=desktop flag, I couldn't get any window (Lofi's main or he debug console) to show. No clue what was happening here.

Electron 14.0.1 is not Lofi's version, it's currently at 11.2.1. I have a branch to upgrade it to 14 but I'm still running into issues with children browser windows

Huh, very strange. Have you tried using this flag when running the electron-quick-start demo? That may give a rough indication of whether the flag works well for you with basic Electron applications, and not just Lofi.
