Cura preview window covered in infinite infill

[cdyrud 0]

Just got back into cura after not being able to open it for a while (fixed by running in windows 8 compatibility). I put a file in and sliced it no problem, but when I tried to look at the preview, the infill had gone wild. The build area, and as far as I could see in all directions, was completely covered from the lowest point of infill in the model to the highest. When I turned the infill percentage to zero it went away, but it seems to be that 1% and higher infill does this. Tried switching infill pattern as well with no change. Cura 4.4 on windows 10.

Looks like a rendering issue. What GPU do you use?

Does this also happen if you switch Cura to "compatibility mode" in the General preferences and restart Cura?

I have an Intel HD Graphics 620. As stated, I need to run in windows 8 compatibility mode for cura to open.

That's not the compatibility mode I was talking about. Cura has a built-in compatibility mode that uses OpenGL 2 instead of OpenGL 4. See the "Force layer view compatibility mode" option below:

Seems to have solved it. Now would this be a normal appearance in this mode? No infill to be seen, tried it on several percentages. I think the time to print changed with the change in infill though, so I would assume it's still there.

 

And because it happened just now, any idea why cura will randomly be unable to slice? Or would that be a question for a new thread?
