--- Comment #7 from Vlad Zahorodnii <vlad.zahorod...@kde.org> --- Based on drm_info output │ ├───CRTC 0 │ │ ├───Object ID: 53 │ │ ├───Mode: 2560x1440@199.99 driver phsync nvsync │ │ ├───Gamma size: 256 │ │ └───Properties │ │ ├───"ACTIVE" (atomic): range [0, 1] = 1 │ │ ├───"MODE_ID" (atomic): blob = 114 │ │ │ └───2560x1440@199.99 driver phsync nvsync and wayland session log kwin_wayland_drm: crtc 53 kwin_wayland_drm: "MODE_ID": 114->108 it indeed looks like kwin tries to change the mode with refresh rate of 199.99Hz to (I guess) 244Hz, but the atomic test only commit fails (perhaps due to bandwidth limitation?). Can you try unplugging the other output? -- You are receiving this mail because: You are watching all bug changes.
