Current result

• The popup is displayed but all the choices are black windows
• error message : [x11grab @ 0x7f5768819800] Cannot get the image data event_error: response_type:0 error_code:8 sequence:16 resource_id:968 minor_code:0 major_code:73.

Same / similar issue: #1242

Can you provide logs before this error?

I just reproduced the bug, here are the full logs. log.txt

added wait-for-answer label

Hi I have a similar issue, but for me the first time I open the application the screenshare works for one second (showing screen thumbnails and streaming starts and is visible on other end) but after roughly a second the stream freezes and when I stop screen sharing and try to share the screen again, I get met with the black window thumbnails and the stream not working if I try to screen share anyways.

• OS: Arch Linux
• Jami version: 202403310008
• What build you are using: jami-client-qt

I really hope this can get fixed because I was looking into Jami precisely to video call and share my screen (currently stuck with Discord). If there's anything I can do to help out more please let me know!

Thanks for bringing this to our attention! I'll try to figure out what the problem is. Can you send us Jami's logs when you try to share your screen?

Maybe related (window sharing): #1242 (comment 48180)

@ffauteux-chapleau When I open the logs from within Jami it doesn't seem to list anything from when I started the call..

@programger Sorry, by "logs" I just meant everything that gets printed out when Jami is launched from a terminal. The first line should look similar to this:

client	[1712074347194][INF][7c9f5dd1cf40]: Using Qt runtime version: 6.6.1

So yeah, just start Jami from a terminal, go through the steps you mentioned (i.e. try to share your screen, wait for it to fail, stop, try again), close Jami, and then send me everything that was output in the terminal.

@ffauteux-chapleau Here are the logs from the CLI:

So the error message OP posted does not show up here..

@programger I tested on my laptop (which is also on Arch) and I got both types of error (the one in the OP as well as the one you got). They may not be related but I'm not ruling that out for now.

Just to be sure: are you actually on X11 like the logs suggest, or are you on Wayland? I'd also like to know what you get if you run the following command: ldd $(which jami) | grep libav

@ffauteux-chapleau I am on the X11 KDE Plasma session. I doubt I would get the initial screen thumbnails under Wayland, no? Anyways, here's the output:
