White Streaming window without controls

[gn0m3r4l]

Hey there,

I downloaded and started version 1.3.1 (with and without admin priv.). I get the mentioned two windows and can drag them both.
But the streaming window is always empty (completely white). I do not even get any control panels like a close button.
Do I need to start a Teams Call for showing the content?

I haven't seen that happening... Which version of windows are you running? Does it work on another device or another user account?

[gn0m3r4l]

Unfortunately I cannot test on any other device.

By accident, I noticed that it seems to be a display issue.
I run my internal notebook display aside of an 49" widescreen (Samsung G9, connected via displayport) display. 49" is main display, extending to the 15" notebook display.

If I move the red bordered windows over to the internal display, the preview window shows content. But as soon as I move it back to the larger display, the described white content appers.

Oh I see, I think multiple displays and/or their arrangement is causing the problem. Will it work if you turn your notebook display off? I can also try to reproduce this issue if you could share your exact display arrangement settings

[gn0m3r4l]

Notebook display off won't fix.
Seems to be related to the main display. Display is: Samsung Odyssey G9 Curved Gaming Monitor C49G93TSSR, 49 Zoll

By quickly viewing your code, you handle high dpi in a special way. Could this be related?

[gn0m3r4l]

I downloaded you code, running it in intellij or vs code. Which is the main class to be started? npm install causes errors for me

[mPyKen]

npm install causes errors for me

On my end it works with node version 14.17.3 and npm 6.14.13

you handle high dpi in a special way

you can try running the executable with --consider-scale parameter which causes not to forcibly set scaling factor

[gn0m3r4l]

I will try tomorrow morning and keep you up to date

[gn0m3r4l]

I updated my node version which seemed to be the installation problem.

But:
Running from intellij with "npm run", it won't work even as descriped above. Both windows open, but dragging the recording window only displays the new location in IDE log.

[mPyKen]

I am out of clues... sorry

@mPyKen hello. I'm facing the same issue when I enable "10-bit pixel format" in AMD software.

[mPyKen]

I see, interesting! thanks for reporting. I don't have a 10 bit pixel format monitor, it will be tough to figure out how to solve this...

[Kotaless]

Let me know if you need log or tester. Thanks for your work.

Not sure if it can be helpful but there is a similar software working fine on 10-bit.

RegionToShare is using .NET and does not depend on electron which seems to be the problem here:
related electron issue links to chromium issue. If you start a meeting application within chromium and try to share some content, do you see your desktop as an option to select from?

I can share my screen in Edge chromium. Btw I'm not using HDR, just 10-bit color.
