Bug ID: 468235 Summary: Screen refresh rate stuck at 60hz even when set to 144hz in the display settings Classification: Plasma Product: kwin Version: 5.27.4 Platform: Other OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: compositing Assignee: kwin-bugs-n...@kde.org Reporter: leguen.yann...@gmail.com Target Milestone: --- SUMMARY *** My display comes with 4 different refresh rates: 60hz, 120hz, 144hz and 165hz. Since kwin 5.27.4, the screen refresh rate is stuck at 60hz whether I select 60hz, 120hz or 144hz from the Plasma display settings (confirmed by checking the screen OSD menu). It happens on both Wayland and X11 sessions. xrandr displays the selected refresh rate. Setting the refresh rate to 165hz works as intended though. Downgrading to kwin 5.27.3 solves the issue. *** STEPS TO REPRODUCE 1. Select a 120hz or 144hz refresh rate from Plasma display settings 2. Moving the mouse cursor / windows around seems sluggish 3. The screen OSD confirms that it's still running at 60hz SOFTWARE/OS VERSIONS Linux: Arch Linux KDE Plasma Version: 5.27.4 KDE Frameworks Version: 5.104.0 Qt Version: 5.15.8 ADDITIONAL INFORMATION My display is an Iiyama G-Master GB2770QSU-B1 -- You are receiving this mail because: You are watching all bug changes.
