Hello,
I’ve been having an issue for a while now with scrolling in Sublime Text. My environment is KDE Plasma on KDE Neon, though this also occurred when I used to use KDE Plasma on Linux Mint.
I generally keep Sublime on its own virtual desktop at all times. I switch between virtual desktops either using keyboard shortcuts or by clicking on them on the Pager widget. Here’s the issue I’m experiencing:
If I switch to any virtual desktop by clicking on the Pager, then, sometimes (seemingly at random, but with high probability), scrolling with the mouse wheel will stop working in Sublime. This also occurs 100% of the time if I scroll while a KDE system notification is displayed in the corner of my screen. This affects scrolling in both the currently-displayed document and the tab bar.
Clicking on the document or tab bar sometimes fixes it, but not always. Switching from Sublime’s virtual desktop to a different one using the keyboard also often fixes it, but, again, not always.
This issue only affects my physical mouse wheel; scrolling via my laptop’s touchpad always works no matter what.
If I recall correctly, this issue began with the Sublime update that gave the entire UI a visual refresh (I think that’s 3.0). I also just downloaded Sublime Text 2 to double-check, and it does not have this problem.
This could definitely be a KDE bug of some kind, but Sublime Text 3 is the only application I’ve ever experienced this issue with. Scrolling always works perfectly fine in all other programs I’ve used (including, as I mentioned, Sublime Text 2). For that reason, I figured this would be the most appropriate place to ask about this.
Thank you in advance for any help or advice!
