Committed on 09/09/2026 at 21:45. Pushed by vladz into branch 'Plasma/6.7'. backends/x11: Fix pixel clock overflow XCB exposes dot_clock as uint32_t, and storing it in int overflows for high-bandwidth modes. For example, 3840x2160 at 240 Hz has a dot clock of 2332000000. The resulting negative refresh rate wraps to 4294765262 mHz and creates a zero-interval offscreen frame callback timer, making kwin_x11 consume an entire CPU core. Use 64-bit arithmetic for the refresh-rate calculation.
