Bug ID: 442240 Summary: On wayland certain screen configurations severely limit frame rate to the point of being unusable Product: kwin Version: git master Platform: Neon Packages OS: Linux Status: REPORTED Severity: major Priority: NOR Component: platform-drm Assignee: kwin-bugs-n...@kde.org Reporter: carlosdema...@gmail.com Target Milestone: --- On kwin_wayland master, certain screen configurations makes performance (fps) plummet. When my Intel based laptop is using dumb buffers on the Nvidia driven external output(s), certain configs work at 30-60 fps whilst others at 5-15 fps - rendering it virtually unusable. When the Intel screen is placed to the left or to the top in a two monitor config, performance is good. When the laptop screen is placed to the right, to the bottom or cloned, performance hits a brick wall.. The fps kwin effect places itself on the external screen in these instances. Performance used to be decent in any configuration but has definitely worsened with the heavy refactoring of late.
