So I just noticed something, when I’m using SublimeText and alt-tab away to another window, and then back, it now (not sure when it started happening), the cursor is a bit taller than it is usually, and it doesn’t blink or change position. I can still use the arrow keys or mouse to change where text is actually entered, but the cursor doesn’t visually move there.
If I open up a new tab and copy/paste what I was working on, the cursor moves just fine. Until the next time I alt-tab away.
Running Build 4152 from the Debian https://download.sublimetext.com repository, Debian 12.1 (haven’t updated to 12.2 yet) with KDE Plasma.
