xlibre migration

[magiruuvelvet]

Migration Plan

• add xlibre overlay and check overall compatibility (toolchain, use flags, drivers, etc.)
• wait for stable release
• migrate back to X11 session (finally no more broken Wayland mess, mix-and-match of components works again: KWin + Picom + KDE Plasma Shell)
  • optional: maybe look for another window manager to replace KWin
  • new plan: move away from KDE entirely since they want to phase out X11, just keep the standalone apps (Qt will most likely keep X11 support for the foreseeable future)
• fix HiDPI setup (some applications react to the XWAYLAND extension that is present in the Xwayland server regarding scaling, this should be possible to replicate without the XWAYLAND extension)
  • fix mixed-DPI setup across multiple monitors (possible, but depends on X clients supporting this)

Interesting Finds
