TL;DR:
Big fat warning to everyone, who's using X11 session on Debian (especially, laptop users):
DO NOT UPDATE.
Issues I experiencing right now *AFTER* migration Debian 12 -> 13 on X11:
1. kwin_x11, kscreenlocker_greet, Xorg and ksmserver are eating CPU as hell after screen is locked: known issues in KDE6/QT6, affected versions Qt 6.8, 6.9 and 6.10, fixed in Qt 6.9.2 and 6.10.0. Guess which version of Qt is used in Debian 13.
2. "Disks & Devices" applet is reporting wrong disk state (mounted/unmounted) when disk have Device Auto-Mount enabled "On Attach".
3. Track-point device, touch-pad and Bluetooth mouse now is treated as a single device without a way of separating settings for them. Yep, touch-pad settings tab says "No touchpad found". Right now I basically need either agree with changed way of navigation in CAD and browsers with my mouse, or forget about using scroll with my track-pad, or switch the "Press middle button and move mouse to scroll" on every occasion of switching input device.
And all of these I found in just two days of using this release.
I need to stress the fact that before the update, when it was Debian 12 and KDE5 it was working smoothly, as expected and with all settings accessible from UI. Now, to fix all of this, I need to crawl configs, add scripts, workarounds and so on. It looks like Debian updates now needs to be ignored the same way as it happening with Ubuntu (3+ month), MacOS (5+ month) or Windows (don't).
Seeedstudio is such ignorant to their customers. Delivery of my order failed due to local mail and person from other side of customer "support" email rejected even to write a request to mail service. I'm not talking about compensation and/or resend.
