Youtube videos are played very smoothy, but the browser itself seems to be cropped around the video (see attached example).

So we found the following RegKey to solve this issue:

Due to the limitation of CEF(Chromium Embedded Framework), client endpoint GPU needs to be disabled if DPI scaling factor is set to a number other than 100% in order for BCR feature to work.

I’m also having issue with BCR on firmware 11.02.156 and HP T630, h264 codec is enabled and the VDA is at 1909.

@member: Thank you for your reply. I can’t disable h264 GPU – only “automatic, H.264 Deep Compression Codec, JPEG” is available (see screenshot) or is it disabled with unchecked “Accelerated H 264 Deep Compression Codec ?

@member does this happen on several Devices (different GPUs)? I assume you already tested different Workspace Apps, right?

I have sent you a Link to a Private Build with Workspace App 19.10

@member Thank you for the link. We cannot use IGEL OS > 10.06 because of the new licensing in 11.x. Is Workspace App 19.10 also available on 10.06 ?
