Following last week's release of Plasma 6.8, the Plasma 6.8.1 point release is out today with dozens of bug fixes.
KDE Plasma 6.8.1 shipped today as the October bug-fix release for this newly-minted desktop. Plasma 6.8,1 brings a possible crash fix for KWin's QPA code, several Wayland fixes including a new KWIN_WAYLAND_SUPPORT_COMMIT_TIMING_V1 environment variable for toggling the commit timing support, a KWin multi-GPU swapchain workaround for NVIDIA GPUs, several Plasma desktop and workspace fixes, and lots of other mostly-small bug fixes.
The full list of fixes with Plasma 6.8.1 can be found via today's announcement and downloads available from KDE.org.
