Strange behaviour on Safari ping/pong shading flowmap example about curtainsjs

[droplab]

Hi @martinlaxenaire, thanks for the reply. I wanted to share this solution for future reference or in case you wanted to update your example.

After doing some additional testing we discovered the issue is that Safari is throwing too many mousemove events that seem to be interrupting rendering performance. Throttling the mouse events down to fall within 60fps or lower solves the issue.

Cheers!

Hi @martinlaxenaire, this FEELS like a pointer event (x,y,delta etc...) normalization issue not necessarily an issue with the library or the shader itself. Perhaps the pointer event data coming in from Safari is either out of the expected range and/or is below a threshold.

Many thanks for the great work on this library!

So it sounds like this may be due to Safari throttling mouse events internally... seems doubtful that there would be any external fix possible for this.

Hey @droplab,

thanks for the detailed bug report, however as you've already noticed, this seems to be caused by how Safari handles mouse events and not the lib itself.

Cheers,
