A Variety of Screensharing Issues

[AdalynBlack]

Describe the bug

• impossible to stream fullscreen applications. Normally in Discord, it has some issues, but if you alt tab to the fullscreen application and back, it shows up for a bit, then disappears, and if you click it during that time, you can stream it. On Vesktop, there simply is no way to stream a fullscreen application. The best I've gotten is by making it windowed mode, streaming it, then going to fullscreen, at which point it only sends a new frame every time I alt tab from the game.
• stream enters an infinite loading screen initially, with the only way to fix it being to go to the stream options and switching applications, at which point it works fine. Also, there's no way to customize the bitrate, which while not an inherent bug, is somewhat annoying if any parties have a poor internet connection.

To Reproduce

Steps to reproduce the behavior:

1. Start a call
2. Attempt to stream a fullscreen application
3. The fullscreen application doesn't appear as an option
4. Attempt to stream a windowed application
5. The stream loads forever and never shows a single frame
6. Change windows to any application/screen (including the current one)
7. Stream suddenly works?

Expected behavior

Streaming a screen or application works, regardless of windowed or fullscreen status, and works on the first attempt without needing to switch the stream target to make the stream actually start.

The second issue is that the stream enters an infinite loading screen initially, with the only way to fix it being to go to the stream options and switching applications, at which point it works fine

issue either with discord or your desktop environment. this even happens on stock discord sometimes

[Vendicated]

as for your other issue, any reason you can't just share the monitor the fullscreen app is on?

[AdalynBlack]

For the second issue, I've never had that happen on stock discord. I also can't exactly change my DE given that I'm on windows. I might be able to mess with some settings, but I wouldn't know where to start with that even. I'll check for a driver update, but I have my doubts that it will help, given that it worked fine yesterday when I first installed it, and I've never had the issue on Discord/Vencord with everything else otherwise being the same

For the first issue, that's the workaround I've been having to use. That or switching to borderless windowed, but some apps don't have that. It's just not exactly convenient, nor is it really the same given that, should I ever alt tab (I only have one monitor), viewers will be able to see everything going on. It also means that desktop audio will be streamed rather than just game audio, and that notifications will show up in stream

I can share full screen applications just fine

Interesting
For me it's always been a bit buggy on Discord/Vencord, with the option only showing for a second or so after alt tabbing
With Vesktop, it just flat-out doesn't show up
Are you using windows? And if so, what version, and what graphics drivers?

Using Arch Linux, Latest Nvidia drivers

[AdalynBlack]

I see
I'll update my graphics drivers and test once I get the chance to. I'm also using NVidia, but I'm also a version or two behind right now I believe

Also, I had a friend that had the same issue the other day, and they're running AMD. I can ask what driver version specifically if that helps for debugging

[AdalynBlack]

I checked my drivers, and I am using driver version 31.0.15.4617, which appears to just be another name for version 546.17. I am using this with an RTX 3070 from ASUS

[Vendicated]

drivers shouldn't have anything to do with this. i made the desktop comment referring to Linux desktop environments, it doesn't apply to windows

[Vendicated]

im not sure how fixable this is. screenshare framework is provided by electron/chromium and the one calling it is discord, so both issues are out of our control. maybe there is some weird workaround for fullscreen windows but it seems like it's a chromium limitation

try opening discord.com/app in a chromium based browser (like edge or chrome) and see if you can share full screen apps in them. if not, there's likely not much we can do
