This bug has had its resolution changed, but accidentally has been left in
NEEDSINFO status. I am thus closing this bug and setting the status as RESOLVED
to reflect the resolution change.

just played along with v4.1.1.

It seems to work. I was able to span krita across both monitors. Monitors do
have different scaling factors. I also moved the app window completely from one
to the other monitor and back. Received no artifacts.

>From my perspective, it's solved.

Can you still reproduce this issue with Krita 4.1 or newer?

I see, sorry for the confusion. I'll see if I can reproduce it.

Aah ... ok. Thanks for the clarification, indeed I missed the point. It is true
that both monitors work with different scaling factors.

Note that if I completely move the Krita window to the other monitor the effect
also happens. It is not only because Krita spans two monitors.

It's not the resolution that matters, it's the scaling factor. The two monitors
can have different even if they have the same number of pixels.

To me, it looks like the first monitor has a scaling factor of 100% while the
second monitor is set to 125%.

It is unmeaningful to try to fix any weirdness when a window spans monitors
with different scaling, because there is not a correct and "expected" behaviour
for any applications when a window is under this state (at least on Windows).

The cursor artifact might be a bug, but unless it also happens when the Krita
window is completely inside the area of one monitor, it does not make sense for
anyone to try to figure out what's happening, let alone "fixing" anything.

Both monitors run at 1920 x 1080. Anyway, I still think it should not happen
that the indicator shows artifacts.

What happened here is that the Krita window has spanned two monitors with
different display density. The window is supposed to adjust the scaling
according to which monitor it is on, but since there are more than one monitors
to choose the scaling from, the behaviour is sort of undefined.

If you want a proper behaviour, the Krita window must not cross multiple
monitors with different display scaling option. Either set both monitors to the
same scaling in the Windows display settings, or resize the window so that it
fits within one of the two monitors.
