Update Screen tooks 3 seconds

Dear All,


I have kernel 3.10.53 and a display with a resolution of 1280x1024  connected via LVDS.

I use the framebuffer driver with X-server because the cpu-load of vivante is 3 times higher than the fb-driver.


When the hole screen has to be updated on my display rotated by 90 degrees I see how it updates it from left to right, so I see on the left side the a part of the new screen and on the right side the last part of the previouse screen.


When the rotation is set to 0 the update works like it should.


Do you have any idea how to speed up this.


Here is my /etc/X11/xorg.conf


Section "Device"

    Identifier  "i.MX Accelerated Framebuffer Device"

    Driver      "fbdev"

    Option      "fbdev"     "/dev/fb0"

    Option    "Rotate"    "CW"

    Option      "HWcursor"  "false"



Section "ServerFlags"

    Option "BlankTime"  "0"

    Option "StandbyTime"  "0"

    Option "SuspendTime"  "0"

    Option "OffTime"  "0"



Section "Screen"

    Identifier "Screen0"

    Device     "i.MX Accelerated Framebuffer Device"

    Monitor    "Monitor0"

    DefaultDepth 16



Kind regards
