Hello Forum!
I don’t know if this is a bug. I have a python script that I used for batch export JPG from layout using capture to bitmap. The script works fine in R7, but in Rhino 8 it produces only white images (sizes and dpi remains correct).
This is a simplified script. Thanks in advance for anyone chipping in 
# -*- coding: utf-8 -*-
import scriptcontext as sc
import Rhino, System, os
def export_to_jpg(layouts, folder, dpi=150):
if not layouts:
print("No layouts to export to JPG.")
return
for layout in layouts:
layout_name = layout.MainViewport.Name
filename = "{}.jpg".format(layout_name)
full_path = os.path.join(folder, filename)
print("Exporting JPG:", layout_name)
settings = Rhino.Display.ViewCaptureSettings(layout, dpi)
bitmap = Rhino.Display.ViewCapture.CaptureToBitmap(settings)
if bitmap:
bitmap.SetResolution(dpi, dpi)
bitmap.Save(full_path, System.Drawing.Imaging.ImageFormat.Jpeg)
print("✔ JPG saved:", full_path)
else:
print("✖ Failed to export JPG:", layout_name)
def main():
# Get all layouts
pages = sc.doc.Views.GetPageViews()
if not pages:
print("No layouts found.")
return
# Default folder = Downloads
folder_name = os.path.join(os.path.expanduser("~"), "Downloads")
# Run export
export_to_jpg(pages, folder_name, dpi=150)
# Try to open the folder in Explorer/Finder
try:
os.startfile(folder_name)
except:
pass
if __name__ == "__main__":
main()
System infos - assuming not that much impact on this, I still work with both R7/R8. Same plugins for both

Relevant topics that I could find is this, but it seems that it should have been fixed?
