Bug ID: 103999
Summary: 4x MSAA with RG32F shows garbage on triangle edges
Product: Mesa
Version: 17.2
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/Vulkan/radeon
Assignee: mesa-***@lists.freedesktop.org

Bug

On 17.2.6, edges don't resolve correctly in MSAA.
I'm using pResolveAttachments for this.
I could upload a renderdoc trace, but it's too big for the tracker (90MB).
Tested on RX470.

Are you saying it worked with 17.2.5?

No idea, haven't tried this on any other drivers.

RADV that is. Works on other driver stacks I've tested.

Is this still an issue as of git master with the recent multisample resolve
fixes? (e.g. has commits up to
