Bug ID: 487759
Summary: Vulkan wayland native windows go crazy when in
fullscreen at random.
Classification: Plasma
Product: kwin
Version: 6.0.4
Platform: Other
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: c9lyw0...@mozmail.com
Target Milestone: ---

Example with Minecraft running on Vulkan thanks to the vulkanmod (should work
properly)
SUMMARY
Apps open in random screens instead of the main (and focused) one, and they
flicker a lot while focused.
STEPS TO REPRODUCE
1. launch your favorite Vulkan app with Wayland native mode
2. set it in fullscreen.
3. done.
OBSERVED RESULT
The apps open on wrong (random) screens, and flicker while in fullscreen.
Sometimes they don't have an issue, sometimes they do. It's random... Hardly
trackable because of lack of ways to get logs.
EXPECTED RESULT
The apps should run normally, without flickering.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Void-Linux 6.9.2
KDE Plasma Version: 6.0.4
KDE Frameworks Version: 6.1.0
Qt Version: 6.6.0
ADDITIONAL INFORMATION
- I can't find a way to get logs.
- The issue doesn't seem to happen with my Void-Linux laptop, that runs the
exact same config.
- Dmesg prints nothing
- the vulkan loader debug mode (VK_LOADER_DEBUG=all) prints nothing as well
- Vulkan validation layers print nothing as well.
I try my luck here, after trying on the Void-Linux github repo, then
vulkan-loader repo.
