I cannot reproduce this in current git master, which was recently branched to be become Plasma 6.4. Let's call it fixed in 6.4 until and unless you can reproduce the issue there once you upgrade to Plasma 6.4. Thanks a lot! I can still reproduce this on 6.4.0. I've found that it also happens when turning off the second monitor *and* changing primary monitor resolution at the same time. In this case, I cannot press ' PrtScn' to open Spectacles. Not sure what exactly causes this, but it seems to occur often when I manually block sleep and screen locking (Power Management Applet) and leave the computer for ~8 hours.

SUMMARY After changing the scaling on the primary monitor, sometimes it stops showing the applications that are on that screen in the task manager. I cannot reproduce it consistently. STEPS TO REPRODUCE 1. On a dual monitor setup, enable 'Show only tasks: From current screen' on both taskbars. 2. Launch a couple of applications on the primary monitor. 3. Change scaling (and position) through the terminal with `kscreen-doctor output.DP-1.scale.1,00` and `kscreen-doctor output.DP-1.position.1080,300`. OBSERVED RESULT The applications on the primary monitor stop showing in the task manager. EXPECTED RESULT Show the applications that are on that screen in the task manager. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Fedora Linux 42 KDE Plasma Version: 6.3.5 KDE Frameworks Version: 6.14.0 Qt Version: 6.9.0 ADDITIONAL INFORMATION - I do this very often otherwise games will have the wrong resolution. The primary monitor must be set to 100% scaling and use `Legacy applications (X11): Scaled by the system' prior to launching any game. - This bug goes away if I change the Icons-and-Text Task Manager to Icons-Only task manager (it stays fixed even after changing it back to Icons-and-Text Task Manager). - Changing the scaling back to the prior value makes the applications show in the task manager again. output of `kscreen-doctor -o`: Output: 1 DP-1 enabled connected priority 1 DisplayPort Modes: 1:2560x1440@144! 2:2560x1440@120* 3:2560x1440@100 4:2560x1440@60 5:1920x1200@144 6:1920x1080@75 7:1920x1080@60 8:1920x1080@60 9:1920x1080@60 10:1920x1080@50 11:1600x1200@144 12:1680x1050@60 13:1600x900@60 14:1280x1024@75 15:1280x1024@60 16:1440x900@144 17:1280x800@60 18:1152x864@60 19:1280x720@60 20:1280x720@60 21:1280x720@50 22:1024x768@75 23:1024x768@60 24:800x600@75 25:800x600@60 26:720x480@60 27:720x480@60 28:640x480@75 29:640x480@60 30:640x480@60 31:1600x1200@60 32:1280x1024@60 33:1024x768@60 34:1920x1200@60 35:2560x1440@60 36:1920x1080@60 37:1600x900@60 38:1368x768@60 39:1280x720@60 Geometry: 1080,440 2048x1152 Scale: 1.25 Rotation: 1 Overscan: 0 Vrr: Never RgbRange: unknown HDR: incapable Wide Color Gamut: incapable ICC profile: none Color profile source: sRGB Color power preference: prefer efficiency and performance Brightness control: supported, set to 50% and dimming to 100% Output: 2 DP-2 enabled connected priority 2 DisplayPort Modes: 40:3840x2160@60*! 41:3840x2160@30 42:2560x1440@60 43:1920x1200@60 44:1920x1080@60 45:1920x1080@60 46:1600x1200@60 47:1680x1050@60 48:1600x900@60 49:1280x1024@60 50:1440x900@60 51:1280x800@60 52:1152x864@60 53:1280x720@60 54:1280x720@60 55:1024x768@60 56:800x600@60 57:720x480@60 58:720x480@60 59:640x480@60 60:640x480@60 61:1600x1200@60 62:1280x1024@60 63:1024x768@60 64:2560x1600@60 65:1920x1200@60 66:3200x1800@60 67:2880x1620@60 68:2560x1440@60 69:1920x1080@60 70:1600x900@60 71:1368x768@60 72:1280x720@60 Geometry: 0,0 1080x1920 Scale: 2 Rotation: 2 Overscan: 0 Vrr: incapable RgbRange: unknown HDR: incapable Wide Color Gamut: incapable ICC profile: none Color profile source: sRGB Color power preference: prefer efficiency and performance Brightness control: supported, set to 50% and dimming to 100%
