In Spring Tool Suite with Darkest Dark, when running a project as Spring Boot App, the scrolling in Console reacts with delay.
I found that the issue is caused by Eclipse’s themed Scrollbar, which are used in Eclipse’s Regular Dark theme as well, so the issue is not related to Darkest Dark itself.
A workaround is to add this vm argument in STS.ini
-Dswt.enable.themedScrollBar=false
