Bug ID: 385961
   Summary: using xrandr --transform in order to display a black
bar on skylake leads to weird bugs
   Product: kwin
   Version: 5.11.1
  Platform: Neon Packages
OS: Linux
Status: UNCONFIRMED
  Severity: normal
  Priority: NOR
 Component: xrandr
  Assignee: kwin-bugs-n...@kde.org
  Reporter: xapi...@gmx.net
  Target Milestone: ---

on different testcomputers i manage to use --transform to avoid stretching a
4:3 image to a 16:9 screen..  it properly moves the image to the left edge and
displays a black bar on the right side.

--set 'scaling mode' Center   is not working in these cases because the option
is not recognized on external screens .. this only works on laptops (embedded
displays for me)

therefore i use --transform!

i testet it on a new pc in our school with an intel skylake cpu and it made the
screen flash like crazy once 
and most of the time it properly scales plasma and the area where i can move my
mouse but i can still maximize all my windows to the whole sceenarea

it looks really weird - everything is contained to the correct rectangle, i see
a black bar on the right sight but windows can cover this area nevertheless...






this is the line i am using and i don't think the line is the problem - as i
said it works on all the other computers:

echo "exec xrandr --output $DISPLAY1 --mode $RESOLUTION --primary $TRANSFORM
--output $DISPLAY2 --mode $RESOLUTION --same-as $DISPLAY1 &"

where TRANSFORM="--transform 1.3330078125,0,0,0,1,0,0,0,1" for example in order
to scale the image proportionally to a 1024x768 image on a full hd screen


i tried several other transformations and the result is always the same.
