Description Christopher Snowhill 2018-08-18 12:01:06 UTC
Running Dolphin emulator from dolphin-emu-master PPA, (and the latest (201808170730) build from https://launchpad.net/~oibaf/+archive/ubuntu/graphics-drivers, I encounter this issue with the shadow overlay on Delfino Plaza. I'm linking to both a video and an archived vktrace file.

Can you record a renderdoc trace instead please?
Comment 2 Christopher Snowhill 2018-08-21 04:14:44 UTC
Would that depend on the GPU installed? I kind of pulled that one out after a 6GB memtestCL caused the whole GPU to lock up. I also experienced a Spotify rendering glitch:


I can put it back in and perform the trace, if it’s necessary for this bug report.
Comment 3 Christopher Snowhill 2018-08-21 06:44:25 UTC
Here you go, but it's from a later point in the game, and I don't know if it still triggers the issue.

Comment 4 Samuel Pitoiset 2018-08-21 06:53:49 UTC
According to renderdoc logs you recorded the trace on NVIDIA, is that expected? The trace is incompatible.
Comment 5 Christopher Snowhill 2018-08-21 21:54:36 UTC
And I can't report it on AMD because I removed the card. I can reinstall it if it's absolutely necessary. I really hate constantly swapping my video card out.
Comment 6 Christopher Snowhill 2018-08-21 22:15:22 UTC
Okay, here you go, I was still able to reproduce the effect on AMD:

Comment 7 Samuel Pitoiset 2018-08-22 07:33:04 UTC
Thanks for trace, apparently the issue can't be reproduced with mesa 18.1.6 so it's likely a regression.
Comment 8 Samuel Pitoiset 2018-08-22 10:33:10 UTC
Comment 9 Samuel Pitoiset 2018-08-22 11:58:12 UTC
Should be fixed with https://cgit.freedesktop.org/mesa/mesa/commit/?id=24ee53231da84a1be5ec08abebe8a2ff6aa019ca

Thanks for providing the trace!
