GDAL - virtual raster output issue

[mar0321]

Hi from mapnik version 3.0.23 there is an issue with VRT which cause blurry outputs.
When i use VRT to read ortophoto rasters to make hybrid map then labels are fine but orto raster is blurry, like in bad resolutuon. I also tried single raster in version 3.0.23 and newer and also VRT with just one raster linked and it was correct. The problem is only when u have 2 and more rasters in VRT and i have 1000+ (whole Czechia).
I have to use docker container mapnik which is in version 3.0.18 and it works fine, results raster are sharp and correct.
Can someone check the issue?
Thank you
