Safari bug on VideoTexture repeat

Debugging a website I am building and encountered an issue where VideoTexture was appearing to be clamped rather than wrapping on iOS and Mac Safari. On testing standalone, I found that setting needsUpdate = true on animate would cause a flicker between wrapped and tiled. This occurs on both VideoTexture and Texture.

I’ve set up demos here

I tried a workaround of using h265 encoded mp4, as sometimes that behaves better on iOS but it did not work on this occasion.

Is this a known bug? Any potential workarounds such as other video formats that don’t have this issue?

I believe this post is also related Video Texture RepeatWrapping bug on ios and safari

This topic is a duplicate of Video Texture RepeatWrapping bug on ios and safari.

Since this only happens in Safari, it should be reported at After a quick search, it seems there is not yet a bug tracking this issue.

@Grum What version of macOS/iOS and Safari have you tested with?

Hi @Mugen87
Sure, acknowledged that in the post. Didn’t see any comments or resolutions so made a new thread.

MacBook Pro 13 inch 2017 running macOS Montererey 12.3.1 Safari 15.4 17613.
iPhone 12 Pro Max running iOS 15.5

Created a shadertoy to see if the problem persisted on there and video textures don’t seem to show at all on iOS and the clamp issue is present on macOS. Shader - Shadertoy BETA

I’ll see if I can create a bug listing later on. Needing to do a workaround in the meantime!
Going to try drawing video to canvas and tiling that. Could be clunky though.
