Description pierrescalade 2019-11-04 15:38:32 UTC

SUMMARY
I never aim for the left scrollbar on application, I usually send my cursor to the left, and start scroll.
But with okular I have to precisely (not that hard, but it breaks my habit) place the cursor to grab the scrollbar.  
 

STEPS TO REPRODUCE
1. Open a PDF in full screen
2. Without aiming, place your cursor on the left of the screen
3. Try to scroll in the PDF (using click and drag).

OBSERVED RESULT
The PDF doesn't scroll as if the there where a small margin on the left of the screen where the cursor gets nudged. 


EXPECTED RESULT
The PDF should start scrolling, like in other application.

Works fine for me with the Breeze widget theme: the pixels abutting the screen edge activate the scrollbar just like I'd expect.

Are you using a different widget theme?

Thanks for your fast answer.

I am using the kde-arc theme.

When I try the Breeze theme, it is worse, click drag gets okular to enter window drag mode.

By configuring the breeze application style drag mode from "Drag windows from all empty area" to "Drag windows from title bar only" the same behavior happens as in the kde-arc theme.

I also tested with different Windows border size. 
Nothing, I cannot select the scrollbar.

Can you check the following:

System Settings > Application Style > Window Decorations > Breeze > click the inline edit button that looks like a pencil > Allow resizing maximized windows from window edges

If that's checked, uncheck it and see if that helps.

"Allow resizing maximized windows from window edges" wasn't checked.

|Check the option/test scroll/uncheck the option/test scroll| still nothing, the cursor isn't on the scrollbar.

Updating the PapirusDevelopmentTeam/arc-kde theme with the latest version available in github fixed this issue.

Thanks for your fast response.
