Target Milestone: 1.0
Application: org_kde_powerdevil (6.6.2)
ApplicationNotResponding [ANR]: false
Qt Version: 6.10.2
Frameworks Version: 6.24.0

-- Information about the crash:
weirdness I noticed when logging into plasma6 is that of the 3 screens in use,
2 work as intended, but 1 doesn't wake up properly and seems to be stuck in
640x480. removing the displayport cable and plugging back in results in the
crash. the third screen does recover to normal resolution though.
The reporter is unsure if this crash is reproducible.
-- Backtrace:
Application: KDE Power Management System (org_kde_powerdevil), signal:
