    Hi,

    there are a lot of (heavy) gpu performance issues with display_rotate or xrandr since electron (MM2). It seems like the fps drops from 30fps to 5fps after the rotation. CPU stays the same. Checked that with nmon. I tested a lot of boards (raspberry 2, 3, 3+, Tinker Board, odroid) ,a lot of OS (raspbian, tinker os, xubuntu, lubuntu) and some configurations (OpenGL, amount of modules, electron versions, …). Still the same; more or less.

    As I can see, there is an display object in electron which can handle an rotate option. Does anybody have experience in it? Or perhaps another solution for rotating?

    I’m curious about the answers ;).
