Description t123yh 2017-07-29 14:28:30 UTC 
Sorry, I don't know the name of the behavior but I've recorded two videos to show you the problem:

https://www.youtube.com/watch?v=rK21rQ8Wfo4
https://www.youtube.com/watch?v=CGzDOxKh2YI

Note the random wires between two lines. The problem both exists on Konsole and Ark.

I'm using a Dell Inspiron 7347 with an Intel i5-4210U. The operation system is Manjaro Linux, alone with KDE 5.10.4 and KDE framework 5.36.0 . The display is 1.3x scaled in the System Settings.

I don't know where the problem lies. Please move this to the correct section.

Konsole is bug 373232. Reassigning to ark developers for inspection.
Comment 2 t123yh 2017-07-31 12:52:20 UTC 
I think this is not an application-specific bug, but a global bug somewhere related to rendering. With different scaling and DPI settings, similar things happened even on System Settings and various apps.
Comment 3 Christoph Feck 2017-07-31 14:10:34 UTC 
The referenced Konsole bug is specific to Konsole. If this happens with many applications, it could also be a Qt bug, but it has be investigated individually. I suggest to report it for each application you see it.
Comment 4 Elvis Angelaccio 2017-07-31 14:14:27 UTC 
What I see in the second video is actually the katepart.
Comment 5 Christoph Cullmann 2017-12-20 20:29:48 UTC 
Yeap, we have there some rendering issues :/
