Pinging @Cedric 
I stumbled upon this while me having an issue with never ending pendingData with InternalTexture whenReadyAsync → isReady.
It occurs especially on slower devices. And always, if I add a breakpoint to debug it.
Do you know anything about it?
@sebavan did a fix for the issue reported. Can you provide a playground that repro that on slower device? what do you mean by slower device actually?
Sorry, I meant low powered device, for me it happened to iPhone 12.
It somehow got fixed while resolving problem related to Babylon resizing causing iOS webkit jetsam memory leak event - #11 by mimeeq3d_neal
It’s not a problem now, I can’t reproduce anymore. so strange…
Thank you for your attention!
