Since yesterday, when I try to zoom in using ctrl+mouse scrollwheel then it no longer enlarges the text but it throws at me these popups:
There are about 5 of these popups that I have to close.
I have never had this issue before, I have been using Sublime for about 5 years.
Version 3.2.2 build 3211
This is not standard behavior. A plugin is providing this, likely with a custom keybinding.
How can I find the malfunctioning plugin?
I checked keybindings window and there is nothing regarding mouse scroll wheel or zoom or enlarging text.
Just disable your packages (either one by one or using binary search, whichever is comfortable for you) until it stops happening. That should give an idea of what package might be causing this.
