Description Telesto 2020-04-28 18:58:23 UTC

Description:
SVG is rendered improperly with Skia Vulkan

Steps to Reproduce:
1. Open attachment 160031 [details] look at the image
2. Press F5 -> Compare

Maybe another bug: circles are somewhat 'segmented' (look closely) in presentation mode with Skia/Vulkan Skia/Raster while being smooth in OpenGL/GDI

Actual Results:
Fat outer lines are missing

Expected Results:
Should be shown (compare presentation mode)


Reproducible: Always

Comment 1 V Stuart Foote 2020-04-28 21:04:17 UTC

@Telesto, sorry going to need some screen clips.  

I do see a little difference (voids) in the color gradients, and I do see a segmented effect for the circle outlines--but nothing excessive. Nothing missing or misdrawn.

I'm on Windows 10 Ent 64-bit 1909 with nVidia K2000 with 2020-04-23 build of TB77.

I'm noticing the 'same' issue in authoring mode as your shows. Line thickness is off... 2 fat lines; 3 thin. Fine in presentation mode
