I understand and it's a shame that Vulkan is still not pursued for better usage of the hardware resources. Which would be great for both performance, especially on low-power devices) and for electrical power efficiency, which can help one of the really honorable KDE goals: https://eco.kde.org/ That will be more and more important as the time passes and the global warming and climate changes accelerates. And strangely Vulkan support is something that the Blender developers are pursuing and they don't have a goal like this. Similar with the Gnome / GTK developers who almost 2 years ago started encouraging Linux distribution to build GTK With Vulkan: https://www.phoronix.com/news/GTK-Vulkan-Default-Ahead And later that year GTK 4.16 Released With Vulkan GSK Renderer By Default On Wayland: https://www.phoronix.com/news/GTK-4.16-Released So it looks to me that both Qt and KDE software are falling behind GTK, Gnome and Blender when it comes to Vulkan support. BTW, I did a somewhat similar test with Zink with the help of this environment variable: MESA_LOADER_DRIVER_OVERRIDE=zink And the result is the same, Plasma doesn't load with this either! So both Vulkan and OpenGL on Vulkan through Zink doesn't work! I'll ask the MangoHUD developers if the problem is on their side, but I still find it pretty strange that a program, no matter how bad or what problems it might have to be able to make Plasma not even load and this to not be address on Plasma's side too. If one day someone makes intentionally a bad program or script to break Plasma like this, there will be no countermeasures / protections against that. -- You are receiving this mail because: You are watching all bug changes.
