Bug ID: 421021
Summary: [Wayland] Sometimes, the behaviour of Alt+Tab is
reversed temporally
Product: kwin
Version: 5.18.4
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: tabbox
Assignee: kwin-bugs-n...@kde.org
Reporter: magib...@hotmail.com
Target Milestone: ---
SUMMARY
During intense workflow in a Wayland session, I sometimes find that Alt+Tab
walks through tasks in reverse order (upwards). In these cases, Alt+Shift+Tab
still works as intended (upwards). The issue persists if I let the task
switcher disappear and press Alt+Tab again. I can only deal with it until it
goes back to its normal behaviour (downwards) a few minutes later.
I don't know how to help you debug this, so I will accept any suggestions
(including patches).
I haven't experienced this issue in X11.
SOFTWARE/OS VERSIONS
Operating System: Arch Linux
KDE Plasma Version: 5.18.4
KDE Frameworks Version: 5.69.0
Qt Version: 5.14.2
Kernel Version: 5.6.8-arch1-1
OS Type: 64-bit
Processors: 4 × Intel® Core™ i5-6200U CPU @ 2.30GHz
Memory: 11,6 GiB of RAM
ADDITIONAL INFORMATION
I am using the Wayland session as my default environment. Due to various
issues, I request QT and GTK applications to run as X applications. So, I run
Plasma in the following way:
> GDK_BACKEND=x11 QT_QPA_PLATFORM=xcb startplasma-wayland
I don't know if this is related with the issue, but it is very hard for me to
work in a Wayland session without these settings. Basically, due to issues like
bug 392376, any application can crash at any moment. XWayland clients are a lot
more stable.
