--- Comment #6 from Mike H <[email protected]> --- For anyone able to fix this, a 100% reliable method to reproduce: Be running Wayland session Be running an external monitor, theoretically needs to be displayport as thats how this is connected, to the i7-1355u but it may happen otherwise. At least for me: FADING POPUPS needs to be ENABLED in System Settings: Appearance And Style > Animations [if its disabled, the following produce no effect] - Lock screen (META-L) - Turn off displays (ESC) - Wait 2+ seconds - Turn on displays (any method, i just use ESC again as its a keypress) - Turn off displays (ESC) - Wait 2+ seconds - Turn on displays (Any method once again, mouse, keypress..) As soon as you wake the displays the second time, 3 threads spin in `plasmashell`, 50%, 38%, and 38% core usage for these threads. 1 thread also spins in `kwin_wayland` also at 50% core usage concurrently. Lots of EAGAIN spinning in epoll loops. [What I call 'Core usage' is what `htop` reports in the CPU% column and where I am getting the info from, using htop on my phone ssh'd into my laptop as I muck with this reproduction report.] Please let me know how I can help fix this problem. -- You are receiving this mail because: You are watching all bug changes.
