Can confirm that starting it with "QSG_RHI_BACKEND=vulkan filelight" indeed fixes the problem. This seems to be either a flaw of NVidia's opengl implementation, or Qt/KDEs bug. I noticed that another program written in Qt(86box) freezes when I choose OpenGL renderer, but works fine with vulkan's backend. Also Steam and games seem to work just fine under Proton, but maybe they all use Vulkan and not OpenGl. Running glxinfo doesn't seem to show any anomalies, and glxgears test program performs absolutely fine as well. So this seems to be limited to Qt/KDE OpenGL implementation. -- You are receiving this mail because: You are watching all bug changes.
