When linux-vim 5.11.4-1 and linux-vim 5.11.7-1 when it run smoothly (i.e. without kernel panic), it is very responsive. Even thinking of running KDE Plasma with it. Currently on XFCE. I am on linux-vim 5.11.7-1 (so far 15 minutes uptime). Let’s see whether kernel panic will strike this session. Will keep you updated.
By the way, is Khadas VIM3 21.02 image going to be available?
Edit: XFCE-linux-vim 5.11.7-1 encounter another system freeze after round 2 hours of uptime - running Chromium at the time of the system freeze.
Edit 2: It looks like linux-vim 5.11.7-1 system freeze on GT King Pro is very regular. Had 4 kernel panic just last two hours (2 on system boot up and 2 while browsing).
