+ -- Solutions ?
+
+ If your kwinrc configuration is causing bugs or instability, it’s likely
+ due to version mismatches, deprecated effects, or conflicting settings.
+ Let’s break down the potential issues in your config:
+
+ 1. Version Mismatch ($Version Section)
+ Your [$Version] section includes many kwin.upd entries, which are
auto-generated migration scripts from older KDE Plasma versions. These indicate
your config has been upgraded over time, but if you copied this to a system
with a different Plasma version, some settings may no longer work. For example:
+
+ kwin.upd:remove-flip-switch-effect suggests the "Flip Switch" effect was
+ removed.
+
+ kwin.upd:enable-scale-effect-by-default implies newer defaults conflict
+ with your setup.
+
+ Fix: Ensure both systems use the exact same Plasma/KWin version. If not,
+ reset the config and reconfigure manually.
+
+ 2. Deprecated/Removed Effects
+ Your [Plugins] section enables effects that may no longer exist:
+
+ kwin4_effect_dimscreenEnabled=true: The "Dim Screen" effect was replaced
+ by "Dim Inactive" in newer Plasma versions.
+
+ kwin4_effect_translucencyEnabled=true: Translucency is now part of the
+ "Magic Lamp" or other effects.
+
+ fallapartEnabled=true: The "Fall Apart" effect was deprecated in KDE
+ Plasma 5.25+.
+
+ Fix: Disable deprecated plugins:
+
+ ini
+ [Plugins]
+ fallapartEnabled=false
+ kwin4_effect_dimscreenEnabled=false
+ kwin4_effect_translucencyEnabled=false
+ 3. Conflicting Desktop Effects
+ Some effects clash with others or your hardware:
+
+ wobblywindowsEnabled=true + magiclampEnabled=true can cause rendering
+ issues on older GPUs.
+
+ OpenGLIsUnsafe=false in [Compositing] forces OpenGL, which might not
+ work on Wayland or with NVIDIA drivers.
+
+ Fix:
+
+ Try switching to XRender (for NVIDIA) or update graphics drivers:
+
+ ini
+ [Compositing]
+ OpenGLIsUnsafe=true
+ Backend=XRender
+ Disable GPU-heavy effects like wobblywindows.
+
+ 4. Tiling and Layout Issues
+ Your [Tiling] sections define custom layouts (e.g., horizontal splits). If
the KWin Tiling plugin is missing or misconfigured, this will crash KWin.
+
+ Fix:
+
+ Install the kwin-tiling package (if missing).
+
+ Reset tiling configs or use Plasma’s GUI to reconfigure layouts.
+
+ 5. TabBox Conflict
+ Your [TabBox] uses LayoutName=coverswitch, but
kwin.upd:remove-cover-switch-effect in $Version indicates this effect was
removed.
+
+ Fix: Change to a supported layout (e.g., thumbnails or compact):
+
+ ini
+ [TabBox]
+ LayoutName=thumbnails
+ Steps to Resolve:
+ Backup your current config:
+
+ bash
+ cp ~/.config/kwinrc ~/.config/kwinrc.backup
+ Reset problematic sections:
+
+ Delete the [Plugins], [TabBox], and [Tiling] sections from kwinrc and
+ reconfigure them via System Settings > Workspace Behavior.
+
+ Test with a clean config:
+
+ bash
+ mv ~/.config/kwinrc ~/.config/kwinrc.old && kwin_x11 --replace
+ Log out/in to generate a fresh kwinrc.
+
+ Re-enable effects one by one to isolate the buggy plugin.
+
+ Final Notes:
+ Avoid copying configs across major Plasma versions (e.g., Plasma 5.24 → 5.27).
+
+ Use KDE’s built-in Backup Settings tool (System Settings > Workspace >
+ Backup).
+
+ If the issue persists, share the exact bug symptoms (e.g., crashes,
+ glitches) for more targeted help! 🛠️
