While painting in krita my brush cursor would just turn into arrow along a linear line and when I paint from this point the window would be grabbed and moved. I also reported bug to krita thinking that it would be krita but i used an older version of krita to test this and I found that the behaviour is same on it too. while earlier this same version worked fine. Then I tested this with openbox as wm , the issue is not present there. I also tried libinput as well as evdev driver but the issue persisits. I also guessing this might be wacom driver issue but then it works in other DE and if it was wacom issue it could be reproduced in other Wm as well. Please let me know how to provide more information in order to solve this annoying problem. I cannot paint due this bug report and as a result I was forced to use different WM A video demonstrating the bug is also attached here. P.S. link to previous bug report in krita -> https://bugs.kde.org/show_bug.cgi?id=370455 The reason of marking this "grave" because my work involves painting 8hrs a day and due to this bug I can't use kde with krita so it is practically unusable for me . thank you Reproducible: Always

Which window/widget style are you using? I cannot properly recognize in the video.
It looks a lot like the widget style is triggering a window move. This is something that breeze and oxygen do. The explanation for openbox not triggering it would be that this window manager doesn't support the respective hint. If that's the case we need to bounce the bug back to krita as they need to properly mark the widget as interactive.
I am using default breeze theme , I have windows can cover option enabled in the pannel and moved its position to the top. I have enabled no border on the window , moved the close maximise and minise buttons to left and kept the buttons to small in the settings apart from this I haven't modified anything that is in default breeze theme. Due to some technical reasons krita uses fusion theme hence it looks different.
The default style for Krita is Fusion, and it's in fact really hard to use Breeze or Oxygen because both of those styles are too broken to be used, at least in the versions currently shipped by distributions. So, Krita on startup forces Fusion, which doesn't have that move-by-clicking-on-empty-space-drag feature. I can try to explicitly set the canvas widget to interactive: what is the flag for that?
to add to the information. I have enabled move windows by using title bar only option , and kept the trigger key to Meta(windows) + drag .
Are you pressing the Alt key anywhen during interacting with the window? Could you please provide the output of: qdbus org.kde.KWin /KWin supportInformation
Also could you please switch to the default breeze cursor theme and rerecord the video? The "drag" cursor icon is confusing to me as KWin doesn't use it. I need to see the which cursor icon is used during the drag to evaluate whether that's actually KWin moving the window.
(In reply to Boudewijn Rempt from comment #5) > The default style for Krita is Fusion, and it's in fact really hard to use > Breeze or Oxygen because both of those styles are too broken to be used, at > least in the versions currently shipped by distributions @boud: can we please get this fixed? Having a consistent look and feel is very important for us and Krita is a very important application for our ecosystem. Let's try to work together and prioritize any issues in breeze and oxygen and also get all distributions to ship the fixes. We can do that!
"Are you pressing the Alt key anywhen during interacting with the window?" No I am just left clicking on the canvas with pentip (wacom) .( Although I can reproduce this with mouse too .) I have re assigned Alt to meta key for moving windows i will share the other information in an hour or so. thank you very much for the response.

Thanks for the updated video, looks like it is KWin which is moving the window. I have absolutely no idea how that can happen. KWin itself only triggers the window moving when you interact with the decoration, but that's not what you are doing. So something must be triggering the window move and normally that would come from the application. Could you please run: xev -root > xev.out Trigger the problem, terminate xev and attach the output. This records all X events, so please don't type to not get any sensitive data in.
Created attachment 101667 [details] xev output
I logged into plasma , then opened krita , xterm , I then ran xev and reproduced the problem and then stopped xev by Ctrl + c . the xev output is attached in above comment.
Thanks, I expected to see: ClientMessage event, serial 21, synthetic YES, window 0x3000005, message_type 0x132 (_NET_WM_MOVERESIZE), format 32 which is not there. That means KWin does trigger the move. But why? There are three different ways how KWin could trigger the move itself: 1. Right click window decoration -> More Actions -> Move 2. Click window decoration 3. Modifier+click anywhere on the window Given the videos we can clearly rule out option 1. So somehow we go into possibility 2 or 3. First thing: could it be that your tool triggers the meta key? I have heard that some tablets do that. To rule out please change the setting back to Alt. For the possibility 2: please use xev again but slightly different. Use xwininfo, click on krita. That will give you a window id. Now pass that to xev with: xev -id <id from xwininfo> This will record all motion events. Thus we should hopefully be able to reconstruct where the actual mouse events are, whether they go into the window decoration, but we just don't see it.
I would like to add that i can reproduce this issue with mouse too. so tablet sending meta key press may be doubtful. nevertheless I will reset it back to alt and try this again just to be sure.
Created attachment 101669 [details] xev krita output
I have set the move window key to Alt and reproduced the problem. I ran xwininfo and xev as you suggested. please take a look at the attachement in the above comment
I don't see any key press/release or pointer events there. Shot in the blue. Please restart KWin with the following command: KWIN_NO_XI2=1 kwin_x11 --replace &
I have now installed krtia on my system and are (of course) not able to reproduce the problem. When using the wacom tablet the cursor never turns into a mouse cursor. In fact I cannot leave the drawing area at all while drawing. Which I think is what is expected.
Some investigation results: if one removes the window decoration the problem is not triggered. Krita starts as a normal window and directly maximizes. This might cause a problem with the decoration not having a correct geometry and then accepting events.
I triggered the bug!
Yay! (On the breeze topic, we've got a plan to see if there are any more issues. See https://bugs.kde.org/show_bug.cgi?id=361811 -- and then we can re-enable it, maybe with a version check.)

Git commit 2e3c6c92e94e9902a9c808f6af92aa3afc797fdc by Martin Gräßlin. Committed on 28/10/2016 at 14:06. Pushed by graesslin into branch 'Plasma/5.8'. Trigger resize of input window when deco size changes Summary: Client::updateInputWindow operates with the decoration size. The method gets called from various points when changing the window geometry. If at that moment the decoration has not updated yet, the borders might be at a wrong position. This behavior could be triggered when a window requested to change the state to maximized. During maximization the decoration still had the wrong size when updateInputWindow was called, thus an interactive area inside the window was created. To circumvent this problem updateInputWindow is now also called whenever the window decoration changes. As a note: that a maximized window has resize only borders is wrong. Kwin should be protected against that.
