 Hi Rodrigo I hope this helps 😅
 Thanks Michael! Actually I expressed myself wrong: I don't want to change the size of the mouse cursor (which is the dialog you show), I need to change the thickness of the text cursor (AFAIK, also called 'caret'). (re @Michael: )
 So it would be this one : https://matterbridge.lubuntu.me/676f8aae/file_10377.jpg
 Oh only that special one 😅
 yes 🫣
 the problem is, it becomes almost invisible when typing in a LibreOffice
 I used to change it editing the GTK css files of the theme. But I doesn't work anymore and I don't know how to change that (I guess it depends on LXQt now)
