We have OpenGL Issues in Viewport with Corona Materials. See on Screencapture.
In some projects materials always flicker ans show only wireframe when you move the camera or when you scale objects.

System: OSX 10.14.6
R21 Studio
Corona 5 HF2

Hi there, If you haven't done so already, could you possibly share this scene with us via our private uploader? If so, when saving from Cinema, please use the 'save project with assets' option to ensure all materials are linked to the scene. If it has already been uploaded, can you tell us the file name? Thx in advance.

Hello again, If you switch over to cinema's standard renderer, does this also happen or only when in Corona mode?

I create a special bugreport file and another screencapture to show the issues. This happen only with corona materials.

I have the same problem as shown in the video.
Also, when changing projection type in texture tag, object disappears for a couple of seconds
This happens as long as there is a corona material applied - meaning if a c4d material is stacked to the right it also happens
Only when corona material is removed, the issue disappears.
This is new in V5.

Is this fixed in V6 daily? Didn't see anything in change log.
This makes working in V5 impossible, had to back to V4. Is this a Mac only problem?

Just in case you are not aware, in Corona 5 dragging objects (with corona materials applied) into content browser, makes objects invisible in the preview window.

For now you can disable materials in the viewport to adjust mesh or values.

Hi Core2000,
not sure what you mean by "disable materials in the viewport".
How do you see how a material maps onto an object if it's disabled?

I testet your scene with windows 10 / rtx 2070 / corona Daily V6 and there arent any issues. Could be mac related
