The unwanted ( area or part ) of the panel height appear in this image http://s29.postimg.org/jt5ns17vr/Desktop_1_056.png between two red arrows and runs along panel width. Reproducible: Always Steps to Reproduce: Here is what happen to get this unwanted area and what lead to plasmashell crash: 1. I moved the panel to top edge. 2. Then i Added that line BorderlessMaximizedWindows=true under [Windows] section in file $HOME/.config/kwinrc to remove title bar from maximized windows and it worked :) 3. Now the panel have shadow that cover my windows so i removed the shadow from breeze theme, through an edit to panel background file located in /usr/share/plasma/desktoptheme/default/widgets/panel-background.svgz I delete this lines from the file <rect style="opacity:0.875;fill:#008000;fill-opacity:1;stroke:none" id="shadow-hint-bottom-margin" width="4" height="12" x="44.08107" y="-162.30389" transform="scale(1,-1)" inkscape:label="#rect3884" /> then the panel shadow was gone :) and i ended up to the first image with the unwanted area http://s29.postimg.org/jt5ns17vr/Desktop_1_056.png I spend a lot of time trying to cut this area from the panel here is what i tried: 1- I removed the background of this area from panel background file /usr/share/plasma/desktoptheme/default/widgets/panel-background.svgz I delete this lines from the file <g style="opacity:0.97899996" id="bottom" transform="matrix(0,2,-2.4615385,0,439.53847,-77.00061)"> <path inkscape:connector-curvature="0" id="path3169" d="m 62,129 0,13 2,0 c 6.68e-4,-0.0217 0,-0.0406 0,-0.0625 l 0,-12.875 c 0,-0.0219 6.68e-4,-0.0408 0,-0.0625 l -2,0 z" style="fill:currentColor;fill-opacity:1" class="ColorScheme-Background" /> <path class="ColorScheme-Background" inkscape:connector-curvature="0" style="fill:currentColor" d="m 63.500223,129 0,13 0.5,0 c 1.67e-4,-0.0217 0,-0.0406 0,-0.0625 l 0,-12.875 c 0,-0.0219 1.67e-4,-0.0408 0,-0.0625 l -0.5,0 z" id="path3171" /> <path id="path3173" d="m 63.500223,129 0,13 0.5,0 c 1.67e-4,-0.0217 0,-0.0406 0,-0.0625 l 0,-12.875 c 0,-0.0219 1.67e-4,-0.0408 0,-0.0625 l -0.5,0 z" style="opacity:0.65;fill:#ffffff;fill-opacity:1;fill-rule:nonzero;stroke:none" inkscape:connector-curvature="0" /> </g> Then it become with no backgroud (transparency) so it shows part of my desktop bakground http://s29.postimg.org/pilwcce1z/Desktop_1_057.png 2- I added new default panel and it apeared at the bottom edge. then the unwanted area gone and it now look exactly like what i want http://s29.postimg.org/md5vzvktj/Desktop_1_058.png but ofcorse with another panel in the bottom edge of the screen! so i removed the new defalut panel and a crash happened to plasmashell, then the unwanted area of the panel come back again : ( Application: Plasma (plasmashell), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

I care about every pixel i have so i want to remove this ( area or part ) from the panel. is this possible? Thanks.
as for the borders: Easier thing to do is find the installed panel.qml and change adjustBorders function to instantly return and add enabledBorders: As for the crash I think it's completely unrelated. We're getting a few in a similar trace, and never reproducible. If you can make it continually crash in that same way with some steps I would love to hear it *** This bug has been marked as a duplicate of bug 353031 ***
Created attachment 94883 [details] installed Panel.qml file
Here is my /usr/share/plasma/shells/org.kde.plasma.desktop/contents/views/Panel.qml Attachment #94883 [details] and that what i edit function adjustBorders() { return; var borders = PlasmaCore.FrameSvg.AllBorders; if (!containment) { return; } switch (containment.location) { case PlasmaCore.Types.TopEdge: borders = borders & ~PlasmaCore.FrameSvg.TopBorder; break; case PlasmaCore.Types.LeftEdge: borders = borders & ~PlasmaCore.FrameSvg.LeftBorder; break; case PlasmaCore.Types.RightEdge: borders = borders & ~PlasmaCore.FrameSvg.RightBorder; break; case PlasmaCore.Types.BottomEdge: default: borders = borders & ~PlasmaCore.FrameSvg.BottomBorder; break; } if (panel.x <= panel.screen.geometry.x) { borders = borders & ~PlasmaCore.FrameSvg.LeftBorder; } if (panel.x + panel.width >= panel.screen.geometry.x + panel.screen.geometry.width) { borders = borders & ~PlasmaCore.FrameSvg.RightBorder; } if (panel.y <= panel.screen.geometry.y) { borders = borders & ~PlasmaCore.FrameSvg.TopBorder; } if (panel.y + panel.height >= panel.screen.geometry.y + panel.screen.geometry.height) { borders = borders & ~PlasmaCore.FrameSvg.BottomBorder; } root.enabledBorders = borders; } enabledBorders: and that what happen http://s12.postimg.org/aw9ls0qn1/Desktop_1_055.png thank you.
so what i did wrong and how i remove this borders?
try: function adjustBorders() { root.enabledBorders = PlasmaCore.FrameSvg.NoBorders; }
same result no panel http://s29.postimg.org/7yxl99jrb/Desktop_1_058.png
