SUMMARY Sometimes when I log in my primary monitor is completely black. I found out it was kspashqml, which was stuck at 100% CPU core usage. I can still interact with the underlying desktop and see it with the task switcher, just not see anything in "normal" mode. STEPS TO REPRODUCE 1. Log in. Sometimes it blocks, sometimes it doesn't. It's completely unpredictable. OBSERVED RESULT The primary monitor is black for a few seconds after login. EXPECTED RESULT The splash screen disappear, like it does on the other monitor. SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 6.3.5 KDE Frameworks Version: 6.14.0 Qt Version: 6.9.1 Kernel Version: 6.15.1-3-cachyos (64-bit) Graphics Platform: Wayland ADDITIONAL INFORMATION I can't figure out a way to reproduce it in a constant manner. Sometimes it's every login, sometimes it doesn't happen for a month. It's completely arbitrary. It's also impossible to tell if a new user is affected as well. Does it work there, or is it just luck? I can't tell, because of the randomness of the bug.
> I found out it was kspashqml Can you clarify what this means? Is it that ksplashqml was drawing a black wind over the desktop? Or something else?

Yes, ksplashqml is drawing a fullscreen black window, blocking everything else. (blocking as in visually blocking, the desktop can still have windows and I can interact with them, e.g. opening a terminal and executing commands)
Are you 100% suure that the black window is drawn by ksplashqml? Can you Meta+drag it out of the way and see the normal desktop? If you `killall -9 ksplashqml` in Konsole, does it disappear?

If you `killall -9 > ksplashqml` in Konsole, does it disappear? ksplashqml uses 100% of a core until the black window disappers. If I kill it, the window immediately disappears. I haven't tried dragging it, but alt+tab'ing, grid view, and overview let's me see the desktop.
OK yeah, definitely sounds like ksplashqml is acting up, then. What's your active splash screen? Does the issue still ever reproduce with a different splash screen set, or none at all?

Does the issue still ever reproduce with a > different splash screen set, or none at all? I'm using Breeze and I've never switched. I kind of forgot it's even possible to change the theme. I've tried to force it to occur again, but to no luck. Neither Breeze, Oxygen, nor no theme had any issues. I'll use Oxygen for a while and report back if it happens there too, but given the randomness I can't guarantee when that happens :/

I've had no issues so far, neither with Oxygen nor with Breeze. I can't reproduce it, I can't even get it to occur again. I'm assuming this was fixed in 6.4
