Description

Game Name?

Tested in MK: Double Dash & Super Mario Sunshine

Game ID? (right click the game in the game list, properties, info tab)

GM4E01 & GMSE01

MD5 Hash? (right click the game in the game list, properties, info tab, MD5 Hash: Compute)

What's the problem? Describe what went wrong.

Using vulkan & exclusive ubershaders causes graphical glitches

What steps will reproduce the problem?

Just selecting vulkan as graphics backend & setting ubershaders to "Exclusive" before starting a game.

Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.

Since I failed to compile dolphin myself I could only test the unstable ppa for Ubuntu 16.04 which lacks behind the git repo: 5.0-F7FF634-dirty

Is the issue present in the latest stable version?

Dolphin 5.0 doesn't have ubershaders, so not really

If the issue isn't present in the latest stable version, which is the first broken version? (You can find the first broken version by bisecting. Windows users can use the tool https://forums.dolphin-emu.org/Thread-green-notice-development-thread-unofficial-dolphin-bisection-tool-for-finding-broken-builds and anyone who is building Dolphin on their own can use git bisect.)

Again, could only test 5.0 & 5.0-F7FF634-dirty

If your issue is a graphical issue, please attach screenshots and record a three frame fifolog of the issue if possible. Screenshots showing what it is supposed to look like from either console or older builds of Dolphin will help too. For more information on how to use the fifoplayer, please check here: https://wiki.dolphin-emu.org/index.php?title=FifoPlayer

N/A

What are your PC specifications? (CPU, GPU, Operating System, more)

CPU: Intel Core i5 4690
GPU: novideo gtx 770
OS: (K)Ubuntu 16.04
GPU driver: 384.111

gtx 770 selected as adapter in vulkan backend

Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)

I suppose the issue is also present in "Hybrid" mode but not as noticeable since the ubershader is replaced by a specialised shader right away in these games.

This is likely driver issues unfortunately, there probably isn't anything that we can do about it.

Sounds like bad drivers. Can't reproduce.
