KDE Plasma 6.6.5 Targets NVIDIA Regressions and Bug Fixes

Quick Report

KDE Plasma 6.6.5 is out as a focused bug-fix release, with attention on the NVIDIA driver regressions that appeared after the 595 branch update. The release is not a feature wave, but it does target the sort of desktop rough edges that users notice immediately.

The update improves color handling on NVIDIA GPUs, removes the CI/DCI external display option when HDR is enabled, and fixes multi-GPU behavior that had caused trouble on Wayland and KWin. It also patches Spectacle clipboard handling and acts as a stepping stone toward Plasma 6.7, which is expected to land with larger UI changes later this year.
