[grigosback]

Bug report, debug log and your config file (FULL LOGS ARE MANDATORY)

Debug log Config file

Steps to reproduce

1. Go to remote control
2. Enable System Screen Capture
3. Check Live Video in the LED Visualization window

What is expected?

It should show the current screen image without gif

What is actually happening?

The image looks distorted or glitchy like in the attached picture. This also affects to the LEDs ilumination.

I restored you configuration and test it: works fine. Your path is clear but since I can't reproduce the problem I can' fix it. Maybe it's a matter of your graphic card drivers (tested on GTX1060) or Windows 11 (the screen grabber was designed for DX11, the compatibility should be sustained, I can't guarantee it for MS).

In my case I'm using a RTX2060 connected to an Alienware 17 R3 laptop using an Alienware Graphics Amplifier, so maybe the problem is with my particular setup. What's strange to me is that using the Hyperion Screen Capture software and sending the image to the HyperHDR server with Flatbuffers works, but I think this is more CPU consuming, that's why I wanted to make the native screen capture works. By the way, I have the same problem using v17 and Hyperion.

Seems like a fight for graphic resources and our surface texture is lost/updated while we process it. Hyperion Screen Capture is using different approach but I wanted to avoid full frame scaling: currently we process every n-th pixel to reduce a frame which should be faster.

Other thing: If I setup to use capture the laptop integrated monitor (that is connected to the internal GPU) instead of the external monitor (connected to the RTX2060) works fine

And finally, the image glitches only when it is static, if something is moving it works fine

Is it possible to change this priority? Edit: nevermind, done it but it didn't solve the problem

OK, I know what's probably happening.

The problem should be fixed now. You can find the installer in the latest github action after the build is finished (currently: https://github.com/awawa-dev/HyperHDR/actions/runs/2393373150 ) Let me know if it solved your problem. You need to check that option:

It worked! Thank you so much!
