Qgis: Layout export generates lines in raster dem

[bellanz80]

Describe the bug
Hi. Given a DEM raster, and displayed as shaded on the fly, the print layout generates a line in the exported image.

How to Reproduce

1. Import raster DEM'
2. change the style to shading
3. open the print layout and append the hillshade map
4. export as image, (I use 300 dpi)
5. notice the lines in the exported image

QGIS and OS versions
QGIS 3.10 Windows 10 64 bit

Additional context

the problem appears with all resample (nearest, bilinear etc)
NEAR

BILINEAL

In QGIS 2.18 it works perfectly, there is no lines.
