Garbage being shown when rendering views with transparency #282

Closed ivanonchi closed 7 years ago

ivanonchi commented 7 years ago

Working on an app based on the VideoWidgedDemo, I tried to add views with transparency (UILabel with clear background, image with transparency in UIImageView, etc.) but there were random colors shown in place of transparency.

I fixed it by clearing the context before using it for view rendering, but then the background was black, so I noticed alpha blending was not enabled.

I sent a pull request #274 with a fix to these issues in hopes it is of help.

We recommend you migrate to GVRKit (in the iOS repo) as it includes the same functionality but is much more extensible than VideoWidget (which will be deprecated soon).

Thanks @nathanmartz but please note the provided VideoWidgetDemo I refer to is actually using GVRKit (GVRVideoRenderer etc.), not the deprecated VideoWidget. The project name is a bit misleading 😅 Could you consider taking a look as this is a bug in GVRKit?

Thanks for the PR. We will address this in the next release.
