Flicker in sceneview with mapimagelayers

Question

Hi,

I'm using version 4.13 with a sceneview with mapImageLayers on top. Unfortunately I'm experiencing a sort of flickering when the mapImageLayers are refreshed (i.e. when the extent is changed and new tiles are loaded). The ficker sometimes shows a black background for half a second. I've attached a gif to illustrate my problem. My graphicscard is  AMD FirePro W2100. However, I've tested this on many different machines and the flicker is always there.

Hi there,

Thanks a lot for the detailed information. We were able to reproduce the flickering issue left in 4.14 and plan to get this fixed at 4.15. Your input is very much appreciated.

Best,

Veronika

Btw. The flicker problem is much more apparent if the mapImageLayer contains polygons. Here is an example:

Thanks for the reply Noah. I've found out that the problem only seems to occur in relation to switching between mapview and sceneview in an application. When trying with version 4.14 the black flicker seems to be gone (this was the main issue), but there is still an issue where the mapImageLayer sometimes sort of jumps when it is being redrawn (i.e. after pan/zoom). I've made a sample to illustrate the problem. In the sample you need to click the 3D button down in the left corner to switch to 3D, and then pan/zoom the map so that the mapImageLayer redraws. Please note that the "jumping" does not always happen. It's typically when there is a large portion of the layer that needs to be updated.
