Hello, first of all I am Japanese, so English may be strange.
I found problems with Graphic Drivers while streaming YouTubeLive and NicoNicoLive .That is different preview of Broadcast Software and preview of Live Streaming site is different. Preview of Live Streaming sitwill be cut off by 10 to 50 pixels. YouTubeLive archived videos as well.Please see the image for details(Testing with Radeon Software Crimson Relive Edition 17.5.1, Relive function installed).
I tried to change Broadcast Software and those settings them , did not solve it however, changing the driver improved.
NicoNicolive (NewLive beta) was solved by installing Radeon Software's Relive function, but YouTubeLive issue only improved by changing drivers.
I tested Radeon Software ver 16.9.1 and 16.12.1 , 17.4.2 , 17.4.4 , 17.5.1 , 17.6.1 ,17.6.2 , 17.7.1,They installed cleanly after using AMD Clean uputility.
I tested Broadcast Software OBS(https://obsproject.com/ and https://ux.getuploader.com/OBStools/download/88/BuildStudioOBS_1.333.1903.0.zip , OBSMP_環境構築Plusビルドツール | VariedTasteFinder ) and Niconico Live Encoder
What's causing this? How do I fix it?,Please help me
