Emulator

Game Name?

All games

What's the problem? Describe what went wrong.

With the latest Nvidia drivers, using the Vulkan Backend and going fullscreen at 4K resolution 60Hz, glitched black bars appear in all games.

I'm not a programmer, but apparently, Nvidia added a late revised Vulkan API specification that causes screen glitches with 4k resolutions in full screen. As far as I can understand and researched, the issue is Vulkan swapchains, as you can read here: https://forums.geforce.com/default/topic/1028246/geforce-1000-series/screen-glithes-when-using-vulkan-4k-60hz/

What steps will reproduce the problem?

• Set monitor to 4K, 60Hz
• Use Vulkan Backend
• Load any game
• Go to fullscreen

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

5.0-5876

Is the issue present in the latest stable version?

Yes

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.)

All versions

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

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