Running TW, zypper dup on a daily basis (kernel 6.3.2-1-default), KDE/Plasma, X11
desktop machine with ASUS motherboard, AMD processor, AMD video, 64 gb RAM.
First off - this is not a critical problem - doesn’t appear to affect anything, except the visual delay. However, it is a behavior that showed up after a recent update (I assume). Also, this happens only with the desktop, not my laptop. The problem never existed previously
Problem:
Okay, when the desktop boots up, and KDE/Plasma is about to display the Desktop, most “everything” shows up - Conky monitor, KDE Panel at top, Latte Panel at bottom.
However, the Desktop icons show up 20-22 seconds after all those other Desktop visuals. The timing is very consistent - I’ve timed it a couple of times - exactly between 20-22 seconds. Also, if I click on some application (for example, a browser or Konsole or Dolphin icon),it will NOT be displayed until AFTER the Desktop icons are displayed.
I’m not the deeply technical troubleshooter, but I did some brief research on here and read a post or two about a “Logitech mouse” problem (I have a Logitech M510 wireless mouse with USB adapter), and I have run these commands to see if anything obvious is shown (my logic might be wrong).
An INTERESTING observation … if you look at these logs, the last TWO entries in each output are about 20 seconds apart. The mouse works as expected.
