--- Comment #18 from V Stuart Foote <vstuart.foote at utsa.edu> ---
Confirmed the Horizontal lines as the Draw page of attachment 162380 is
scrolled--both Skia Vulkan rendering, and Skia raster. Bands appear at the top
edge as page is scrolled up or down across the top edge of the canvas frame. 

And, with Skia software raster rendering the hang on zoom steps (<Ctrl>+mouse
wheel, or Zoom bar) is very noticible.  Skia Vulkan also slows, but not to the
point of stopping.

I did have on crash out of Skia Vulkan rendering with fall back to Skia raster
with today's TB77 build of master/7.1.0
