Write_image corruption?

I’ve been using a script to batch export views/scenes with a specific proportion different than my screen. I’ve recently upgraded to SU 2025 & now 2026, and I’m getting problems with the output.

For example this console command creates a corrupt image. (The yellow columns)

Sketchup.active_model.active_view.write_image('c:\temp\test.jpg',3750,2250,true)

2026-01-14 20_02_38-test.jpg - IrfanView (Zoom_ 1540 x 924)
2026-01-14 20_02_38-test.jpg - IrfanView (Zoom_ 1540 x 924)274×337 61 KB

But if I match the actual current screen width & height proportion using File > Export > 2d Graphic > Options (4862 pixels wide for 2250 high), I get the correct image:

Sketchup.active_model.active_view.write_image('c:\temp\test.jpg',4682,2250,true)

2026-01-14 20_02_50-test2.jpg - IrfanView (Zoom_ 1908 x 917)
2026-01-14 20_02_50-test2.jpg - IrfanView (Zoom_ 1908 x 917)274×337 60.2 KB

The corrupted image output varies and strangely enough if I double the desired output, it worked fine.

Sketchup.active_model.active_view.write_image(‘c:\temp\test.jpg’,7500,4500,true)

Any suggestions of what is happening and how to avoid?

Use the option hash overload to switch anti-alias on, & etc.

It looks like this might be shadow related.

Are you using the classic OpenGL engine or the new native DirectX engine?
Do you see differences with each engine vs the other?

BTW, I did not find a exact issue reported in the official tracker searching on “write_image”.
