This affects settings(test area), konsole, firefox, korganizer, gnucash,

Some apps are not affected: LibreOffice, emacs, SQL-workbench/J, signal-desktop, chromium-browser, claws-mail, kde-connect,

Do you have the IBus Wayland virtual keyboard (System Settings -> Keyboard -> Virtual Keyboard) enabled?

No. 

However, it's not currently available since I switched back to X11 because Wayland is WAY too immature:
-  Taskbar dies too often
- windows don't respect screen boundaries:
   - often open with title bar off screen 
   - windows taller than screen
- title bar focus ignored unless mouse moved away from title bar and back over it
- text entry fields often miss first characters; most noticeable when opening a new tab and typing into firefox URL/search bar
- no systray icons for claws-mail
- claws-mail active folder highlight switches to a random folder which is not the current folder when mouse moves from main to compose windows
- login: unlike X11, konsoles all open on desktop 1, wasting time re-orgaizing 10 desktops with 3 physical screens
- fewer keyboard keys available (Calc key does not open kcalc as with X11)
- can't do this: kkkkkkkkkkkkkkkkkkkkkkkkk; only k,k,k,k,k,k,k,k,k,k,k,k... (this report)
-  some apps just silently disappear from screen
- double-click (shade) on title bar does not work on all open windows
Too many other issues to recall.
The flickering is gone; but I'll deal with X11 flickering vs all the above...

System updated minutes ago to:
Operating System: Mageia 10
KDE Plasma Version: 6.0.3
KDE Frameworks Version: 6.0.0
Qt Version: 6.6.2
Kernel Version: 6.6.22-server-2.mga10 (64-bit)
Graphics Platform: Wayland
Processors: 20 × 12th Gen Intel® Core™ i7-12700K
Memory: 125.5 GiB of RAM
Graphics Processor: AMD Radeon RX 6600 XT
Manufacturer: Dell Inc.
Product Name: XPS 8950

and problem persists.

Back on Wayland because KDE/X11 has become intolerable:
- plasmashell crashes/restarts many times an hour
- When screens (3 screens: LtoR order 1,0,2) go dark (power saving),  most windows migrate to screen 1

Will see if KDE/Wayland is now more stable than KDE/X11...

On wayland the individual apps are responsible for key repeats. So you would need to report this to the apps or the underlying frameworks.

So you're saying I need to report this against all the following apps (just a sampling)?
I didn't notice this issue on Mageia 9 or the early Cauldron before recent updates.
- konsole
- systemsettings
- claws-mail
- firefox
- korganizer
- LibreOffice (Writer, Calc, Draw, Base)
- Dolphin
- kalarm
- k3b
- kaddressbook
- htop (filter)
- konqueror
- kwrite
- nano

I was running KDE/X11 until moments ago, now on KDE/Wayland - both are affected.
Seems to me something is in common with all those apps...

To be fair;  auto-repeat does work in:
- SQL-workbench/J
- Signal-desktop
- LibreOffice (Impress, Math)
- SweetHome3D
- chromium-browser
- emacs
- okular
- filezilla

Pierre,

I tested this issue with KWrite, Konsole and LibreOffice (Writer and Calc) on Plasma 6.1.3 and it looks like the issue may have been fixed.

Settings: When a key is held: repeat the key (600ms delay)
Keys: Backspace, Del, Tab, Shift+Tab, arrow keys

All the keys I tested did auto-repeat, where appropriate, in all the applications I tested.
Are you able to reproduce the issue on Plasma 6.1.3?

Thanks!

Looks like I'm still on 6.1.2 and I just updated everything and rebooted a moment ago.

The problem appears to be fixed now.  Thanks!

Looks like a virtual keyboard issue on my fedora 40. If use 'IBus wayland' in virtual keyboard I will hit this, switch to 'None' or others it will disappear.

Hi hpt,

The issue you're seeing with IBus wayland is due to an upstream issue:
