--- Comment #2 from [email protected] --- Thank you for the response and for identifying the possible changes involving dual-GPU systems in KDE Plasma 6.8.0. Unfortunately, I do not have the time to perform additional GPU isolation testing or extensive troubleshooting. I have already spent considerable time investigating the issue, collecting diagnostic information, and restoring my system to KDE Plasma 6.7.5, which has noticeably improved performance. I have provided the diagnostic logs and relevant system information in the original bug report. I hope the development team can use this information to investigate and resolve the regression. For now, I will remain on KDE Plasma 6.7.5 until a confirmed fix becomes available. Thank you.
