    Very slow menu navigation in KODI 17 only in web client

    Very slow menu navigation in web client running KODI 17 on LibreElec. Almost 1 second delay between pressing cursor on remote or keyboard and movement on screen. Normal navigation speed in KODI and non web client X-NEWA.
    First became a problem on RPi2 client. Server reboots every night so later KODI 16 client runs ok. If I then reboot the client with the KODI 17 SD card everything works normally until the server reboots overnight. If the KODI 17 card is used first after a server reboot the slow navigation returns. If I then reboot just the client using the KODI 16 card this also has the slow navigation problem which a server reboot cures.

    It looks like the first time a client accesses the server some setting is made on the server and for some reason the RPi2 setup doesn’t like the settings created by a KODI 17 client. I did once see the problem using my AMD E450 powered client and today my temp replacement for the RPi2 an old Pentium 4 running KODI 17 for two weeks today has the slow menu navigation in the web client so reverted to KODI 16! My Celeron client running KODI 17 is still working ok. It does not seem to make any difference which version of X-NEWA I use.

    I'd need to see the debug Kodi logs.

    Thanks Martin below is link to logs.

    Between 12:10 and 12:11 in the web client I moved around the EPG and then up and down the What's New Recordings menu.

    If it helps I can do the same on the PC client which started having the problem yesterday

    What is your definition of very slow? You look to get a screen a second which on the RPi is about all I would hope for. I see once you flooded the client with more requests then any client can handle.

    I also do see these lines

    No accelerated colorspace conversion found from yuv420p to bgra

    which means a lot of math perhaps tasking your CPU. Since you run 1920x1080 are the screens snappier at 1280x720?

    Also I wonder if sub could send the png screens in bgra if he doesn't already?

    Thanks Martin

    The problem goes away if I set the X-NEWA Web Client resolution back to the default 1280X720!! The KODI resolution is set to 1920X1080x50 so remember a few weeks ago setting the the the Web Client resolution to the same. My other TV is 1360X768 resolution so is run at 1280x720 so didnt change the default web client resolution.

    Thanks again Martin
