We fixed a bunch of multisample resolve issues recently, and if it works fine
with mesa 17.3.7 it should be OK on master.

Closing, please re-open if the issue still occurs.

Cool, could try again mesa master to confirm the issue is really fixed? Thanks!

Is this still an issue as of git master with the recent multisample resolve
fixes? (e.g. has commits up to
https://cgit.freedesktop.org/mesa/mesa/commit/?id=a636208ace00e5ba7ddb331362b3e95fd4cea422)

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

Are you saying it worked with 17.2.5?

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-dev@lists.freedesktop.org
  Reporter: mais...@archlinux.us
QA Contact: mesa-dev@lists.freedesktop.org

  --> https://bugs.freedesktop.org/attachment.cgi?id=135833=edit
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.
