I noticed that scrolling in the embedded PDF viewer with [Ctrl]+[mouse wheel] doesn't disable scrolling. I.e. when pressing [Ctrl]+[mouse wheel up], the document get's zoomed in and scrolled up, although zooming to the center of the screen or the position of the cursor would be much preferred (and is the default behaviour in most other programs).
TeXstudio 2.11.0 (hg 6066+:2a9bee6257ec+)
Using Qt Version 5.7.0, compiled with Qt 5.6.0 R
the zooming is centered on the cursor, works fine here.
Let me guess, Arch Linux ?
Yes... So it is a known downstream problem? Then I'm sorry.
No, but Arch Linux is (here) infamous for producing bugs which don't occur anywhere else.
I can reproduce this on a virtualized Fedora 24 with
TeXstudio 2.11.0 (hg 6066+:2a9bee6257ec+)
Using Qt Version 5.6.1, compiled with Qt 5.6.0 R
fixed: hg 6136 (5ff886630857)
Fix confirmed. Thanks!
