YouTube app choppy or blank (opens in new tab)

Unsure where else to ask this question\. The past five or so months YouTube will suddenly either show black is I've checked anther app and come back where the audio is fine\. Only way to fix is to quit and open again\. The other issue is extremely choppy video \(10-15fps\) but perfect audio\. Again, only way to fix is to close and open again\. Dumped cache and tried other fixes without anything working\. Thoughts? Running S24U\.
