I can't reproduce this with system monitor. Can you show your Task Switcher settings (in System Monitor, screen shot is ok)? Is the system monitor you're talking about Plasma's system monitor or another one? Can you take a screen recording of the effect when it happens? Created attachment 181990 [details]
Settings
OK. It's Plasma's system monitor, it just moves horizontally.

Hm, with some settings I can get horizontal scrolling to work while alt-tab is active. It seems I can also get it with vertical scrolling, but in way fewer circumstances (and that was with a trackpoint, where some scrolling events may be horizontal). Can you try (a) turning off "Show selected window" and/or choosing a different switcher (like compact or large icons) to see if it also happens with those? That would help us narrow down the circumstances. It doesn't reproduce with the large icons switcher. Ah, nvm, it reproduces with other settings. Hi - are there other settings that you found could reproduce this issue? I've been able to find one set of circumstances: 1. Have a window active that can accept horizontal scrolling 2. Press Alt+Tab, hold Alt 3. Provide horizontal scrolling input - in my case, my mouse's scroll wheel can be pressed to the side to scroll horizontally 4. As seen in the thumbnail, the originally active window will receive the horizontal scroll input Thanks!

It reproduces with all settings for me afaik. It can also pass vertical scrolling in Chromium. I'm using xorg. |
