Recurrent black screen issue on both Beta and Alpha

Asphahyre commented 4 years ago

Describe the bug When the stream is starting, the cursor appears (drawn from the host) but the screen is entirely black.

System

OS: Gentoo
OS Version: Linux 5.0.5-gentoo #2 SMP Fri Apr 5 16:14:13 CEST 2019 x86_64 Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz GenuineIntel GNU/Linux
Environment: Gnome on Xorg
Application: AppImage
Application Version, Stable (working): 4.8.14 | Client: 2.15.7
Application Version, Beta (worked twice, but not atm): 4.10.13 | Client: 2.15.7
Application Version, Alpha (never worked): 4.10.13 | Client: 2.16.3
Graphic card in use: VGA compatible controller: Intel Corporation Device 591b (rev 04)

Configuration

[x] The user is in input group?
[x] The environment uses Xorg?
[x] VA API detects H264? And H265?

To Reproduce Steps to reproduce the behavior with Beta

Open the Beta launcher
Update the VM
Start the stream
The stream may work (or not)
Update the Shadow on the VM side, “There is a Shadow update”, from within the stream
When the Shadow will be up again, the stream will restart and be black
Restart the whole launcher, and the stream will restart black again —————
Open the Alpha launcher
Update the VM
Start the stream
The stream will be always black

Screenshots

You can see in yellow, at the top, the network usage at 5Mbps while the stream is started.

Additional context That's tested with and without the low bandwidth mode.

Everything (like shortcuts) seems to be ok except the black screen.

Here are the error logs in Alpha, I'm not able to retrieve the same errors on Beta nor prod.

@Asphahyre As the application evolves quite quickly, do you mind checking if this bug is still happening please ?

I have the same issue, with i965 drivers it work like a charm. Once i update my nvidia drivers the stream start but stay black. Or i can see the first image and then it freeze.

Nvidia GPU is not supported by shadow or through this hack but not in a stable state : https://gitlab.com/aar642/libva-vdpau-driver
