Bug ID: 501029
Summary: Key repeats get stuck in terminals from IntelliJ-based
IDEs
Classification: Plasma
Product: kwin
Version: 6.3.2
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: kde-bugzi...@rocco.dev
Target Milestone: ---
SUMMARY
When using the integrated terminal in any of the IntelliJ-based IDEs (IntelliJ
IDEA, CLion, etc.), if you type something in the terminal, then hold the left
arrow key to go to the start of the line, Plasma gets stuck playing the "bell"
sound.
STEPS TO REPRODUCE
1. Open an IntelliJ-based IDE (IntelliJ IDEA, CLion, etc.)
2. Create a new terminal window within the IDE
3. Write something into the terminal (without pressing Enter), then hold the
left arrow key to move to the start of the line
OBSERVED RESULT
Cursor moves to the start of the line, plays a bell sound because it can't go
any further, then repeats the press occasionally.
This is e.g. what happens in GNOME, the key repeat is delayed by a few hundred
milliseconds.
EXPECTED RESULT
Cursor moves to the start of the line, but Plasma keeps repeating the key press
and gets stuck. Bell sound is played repeatedly (audio warning), and journal is
spammed with
kwin_wayland_wrapper[PID]: Key repeat discarded, Wayland compositor doesn't
seem to be processing events fast enough!
To recover, one has to repeatedly try Ctrl+Alt+Fx to get a TTY, then `pkill -u
$USER` (I haven't found the exact process to kill, but killing the IDE and
plasmashell is not enough). I've also noticed that if you don't do this fast
enough, your only way to recover is to restart the system.
SOFTWARE/OS VERSIONS
Operating System: Fedora Linux 41
KDE Plasma Version: 6.3.2
KDE Frameworks Version: 6.11.0
Qt Version: 6.8.2
Kernel Version: 6.13.5-200.fc41.x86_64 (64-bit)
Graphics Platform: Wayland
Processors: 16 × AMD Ryzen 7 5700X 8-Core Processor
Memory: 62.7 GiB of RAM
Graphics Processor: AMD Radeon RX 6700 XT
ADDITIONAL INFORMATION
Tested on IntellIJ IDEA 2024.3 and CLion 2024.3.4. I'm also using zsh (through
OMZ), if it matters. The IDEs appear to be using XWayland, but the issue
doesn't manifest in xterm. I haven't encountered this before (I upgraded to
6.3.2 earlier this week from 6.2), so I'm very confident it's not an IntelliJ
issue.
