Bug ID: 492167
Summary: After the display turns off the plasma session is
frozen for 30 seconds when woken up
Classification: Plasma
Product: kwin
Version: 6.1.4
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: 3myu40...@relay.firefox.com
Target Milestone: ---
SUMMARY
Every time around 30 seconds after the screen turns off to save power, once the
mouse is moved or keyboard key is pushed, the screen is frozen for 30 seconds,
after which it returns to normal and is accepting input and the screen starts
updating. Happens on the lock screen and also when not on the lock screen. The
bug was also reproducible on fedora and is not reproducible while running the
X11 session.
https://bugs.kde.org/show_bug.cgi?id=462846 is similar, but reports that the
issue persists a shorter time and happens only when waking from the lock
screen, so I'm not sure if it is the same issue.
STEPS TO REPRODUCE
1. Wait for the screen to turn off after the set time, then wait another 30
seconds or so.
2. Move the mouse or press a key on the keyboard to try and wake up the
computer.
OBSERVED RESULT
Screen shows a frozen frame (sometimes the one it showed when the screen went
to power save, sometimes one that is right after waking up) for 30 seconds and
is not registering any input.
EXPECTED RESULT
Once you move the mouse or press a key, the inputs should be registered and
shown on the display immediately after the monitor turns on.

I am not sure that the pulseaudio events are connected in any way.
