I'm not even running KWin (or any KDE or any Qt) anymore...



The compositor is suspended because the game asks for that - you can override
that by a rule.
It however hardly explains this behavior nor is overriding it a sane fix to the
problem.

If the artifacts move along the window and are even visible while the
compositor is suspended, the only explanation is an OutputOnly window which is
likely supposed to contain the deco shadows and is for some strange reason not
removed (plus I really thought we'd now have gotten rid of the stupid
window-but-not-the-window shadows)

Also it's not clear whether this is really the cause (see bug #361154, "I can
disable compositing for say the Steam client (in a kwin rule) and launching a
Steam game - does not cause the compositing issues.")
And no: never seen. I've no steam/account, though.

it seems is a shadow something  that why I Cant capture that as a window and it
captures the plasma 5 desktop.

Yes when I move the window the corrupted shadow thingy is moving as well.

As I said before this actually is happening with ALL the 3D Games or any other
application is using opengl
KWIN automatically disables the compositor on launch of a 3D Application or
game which that was not happening before. So is behaving like
disabling/enabling compositor and causing these problems. 

This was not happening before, KWIN was not disabling the compositor thats why
I didnt have any problems.
 I think these problems occurred during the last update.

So noone of you can reproduce that bug... I mean you dont have any
Application/GAME that is using opengl to launch just to see that it disables
the compositor?

That's the desktop window - if the information regarding the compositor is
correct, things turn really weird (could be some OutputOnly window - not sure
whether xprop etc. capture them)

How do the artifacts behave if you move the window? Do the move with it, remain
static or "clear" (ie. the re-exposed region gets fixed)?

Also I have install another  window manager like compiz and set it as a default
Window Manager and it doesnt cause this problem so I assume is something with
KWIN :o?

First it seems that Plasma 5 is disabling composing automatically each time I
start a 3D Game. Why?? I dont have the option to disable in full screen.

"during the problem" has
> Compositing
> ===
> Compositing is not active

Is that correct?
Sounds as if the decoration window still includes some shadow padding?

Can you please dump xwinfinfo and xprop of the damaged area?

Run:
xwinfinfo > damage.info; xwinfinfo > damage.props

The cursor will turn into a "+" twice, just click somewhere into the damaged
area next to the border.
The output will be redirected into two files damage.info & damage.props. Please
attach them *here* - do in general not use paste.kde.org nor dropbox for
relevant bug information, since that information might be lost for future bug
readers. Thanks.

I have posted the 3 text output files in dropbox - folder corruption

https://www.dropbox.com/sh/jjnfxt3qsv7ncih/AABfLxFw93N-SSAEsM7hb0_Va?dl=0

Text files

no problem --> without the problem 
during the problem  --> while running a specific game in sdlmame disabling the
compositor
with the problem --> exiting the game but having the texture corruption

Looks like bug #361477 resp. bug #361154
The weird pattern is that suspending the compositor (SHIFT+Alt+F12) prevents
the problems, but resuming the compositor (what implies a new GL context)
restores the problem.

Please attach the output of "qdbus org.kde.KWin /KWin supportInformation" (w/
running compositor, but the problem doesn't need to be present)
