Hi. Indeed, thanks a lot for the sample app. I have reproduced the issue and it is related to interaction between Angle GLES UWP wrapper and threading. We will likely have a fix for this in 4.4.7 release.

Can you tell me when release 4.4.7 is planned.

@l4nk4b3l We plan to release RC next week and final 4.4.7 by the end of September.

@l4nk4b3l 4.4.7RC1 is now available and should fix the issue.

Closing this, 4.4.7 is now released.
