Bug ID: 488935 Summary: Adjusting Power Profile Affects Display Colours Classification: Plasma Product: plasmashell Version: 6.1.0 Platform: Other OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: Battery Monitor Assignee: plasma-b...@kde.org Reporter: eamonn...@protonmail.com CC: k...@privat.broulik.de, m...@ratijas.tk, natalie_clar...@yahoo.de Target Milestone: 1.0 SUMMARY I couldn't find much information on this so I assume it is a specific bug and perhaps not intended, but if it is intended and I am being silly, feel free to close! When changing the CPU power profile in the Power Management widget, the display colours change. They will become much more washed out at Powersave, but look normal at Balanced and Performance (the display seems brighter at Performance, but that's it). I am aware that some systems allow you to toggle a display power profile and a CPU power profile, but I have not seen them grouped together. I also don't recall this happening on an old laptop I had where I changed the CPU performance governor manually. It also does not happen on my Desktop PC, or if it does, it is not noticeable. But this may be specific to a laptop power profile - or this laptop's power profile, as I could not see information online about this behaviour. The closest I could think of is that the power profile affects how much power the screen could be getting? But even on other devices where you can set a TDP limit, such as the Steam Deck, the screen colours are never affected in this way. I am using a Framework 16 laptop. This could very well be intended behaviour, but I couldn't find information about changing the Power Profile affecting display colours. This problem could also be an OS configuration issue and not something on the KDE side. I noticed this because I was keeping my laptop in Power Save, and when I opened some YouTube videos, the video quality was noticeably poor (like poor exposure or something). STEPS TO REPRODUCE 1. Adjust Performance Profile from a higher value to a lower value (naming and options may be different depending on the CPU) 2. Display colours will become washed out. 3. Turn the Performance Profile back up. 4. The colours will look normal. OBSERVED RESULT Display colours become washed out when turning the Power Profile down. EXPECTED RESULT Power profile should not impact the screen, or if it is intended, there should be an option to tweak this (perhaps a separate option under Displays for this?)
