SUMMARY When using a key with a modifier, that keystroke seems to be stored in the buffer and is entered into the next window STEPS TO REPRODUCE 1. Open at least two windows that can accept text input, e.g. Konsole and Kate 2. In Kate, hightlight some text and press Ctrl-C, but release the Ctrl key before releasing the C key 3. Click on the Konsole window OBSERVED RESULT Observe the letter 'c' appear in the Konsole window EXPECTED RESULT No character should appear in Konsole SOFTWARE/OS VERSIONS Operating System: Fedora Linux 41 KDE Plasma Version: 6.3.0 KDE Frameworks Version: 6.11.0 Qt Version: 6.8.2 Kernel Version: 6.12.15-200.fc41.x86_64 (64-bit) Graphics Platform: Wayland Processors: 8 × 11th Gen Intel® Core™ i7-1185G7 @ 3.00GHz Memory: 31.1 GiB of RAM Graphics Processor 1: Intel® Iris® Xe Graphics Graphics Processor 2: NVIDIA T500 ADDITIONAL INFORMATION Kate, Konsole, and Ctrl-C are just examples. I have seen it happen with Ctrl-A as well, and with other apps like Brave, Slack, etc. It does NOT happen in X11. For example, copying text from Konsole with Ctrl-Shift-C and then selecting Kate will do the same thing.
I can no longer reproduce this bug. Unfortunately, I don't know whether it was resolved in Plasma 6.3 or by simply installing plasma-workspace-x11. Here is more history: - observed details of the bug as described in this bug report - installed plasma-workspace-x11 to determine whether it can be reproduced in Wayland - rebooted, and logged in using X11 - after login, I was greeted with the "Welcome to Plasma 6.3" window - filed the bug report - logged out and back in using Wayland - bug no longer occurs I will try uninstalling plasma-workspace-x11 to see what that may do.
After uninstalling plasma-workspace-x11 I still cannot reproduce the bug. This seems to point to the bug having been fixed in version 6.3. I should also mention that the version details I posted are probably not correct since updates were apparently applied between the last time I saw the bug and the time I reported it. My sincere apologies for the inaccuracy.
I can't reproduce this either on master. I don't think it makes sense to keep this bug open if it's no longer reproducible - it may be fixed or just have been a temporary thing somehow. Please reopen if the issue reappears.
I can now reproduce this reliably. I'm not sure what made the problem go away for a short time, but perhaps it was some remnant of x11 having been installed.
