Bug ID: 97568
Summary: read pixels of MSAAx8 surface stretched
horizontally/vertically
Product: Mesa
Version: unspecified
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/DRI/nouveau
Assignee: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
Reporter: timothy.o.rowley-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org
QA Contact: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
vtk ctest has many failures which appear to be caused by its selection of a
MSAA visual and a missing resolve on the read pixels - the image it gets is
stretched 4x horizontally and 2x vertically.

Tested with ubuntu-16.04 nouveau driver and a GeForce GTX 750 Ti (GM107).

We do none of that right now, and 8x MSAA is laid out in a 4x2 grid for each pixel, so it makes sense that the output would be "scaled up" that way. -- You are receiving this mail because: You are the assignee for the bug.
