[QUOTE="Trigg3r, post: 1264347, member: 164576"] Morning all, So just been messing with this, pulled the source and ran in debug and tried to see what was causing the hangs when moving the window / interacting with the UI. With the client sat doing nothing on the menu screen, there where little spikes when trying to move the window, so trying to drill into those kept showing as handling input events - I thought it may have been something to do with the TouchForm, so tried it with just a standard form but no luck – touch was not causing it. So then tried commenting out some of the message handling in various places, very slight improvements but the issue was still there – it didn’t seem like anything related to MediaPortal :unsure: so on to Google! I came across someone with a similar error, but related to Microsoft Word. The problem turned out to be DPI settings on the mouse! So I have a Logitech G502 and within the software is a “Report Rate” - I had mine set to 1000, so I knocked that down to 125 and... buttery smooth input again! The Logitech software has options of; 125, 250, 500 and 1000, trying the various options the sweet spot seems to be 250, things start lagging again at 500 or above. So I guess you could have some kind of rate limit within Media Portal to avoid the issue with high report rates? Either way, that’s sorted it for me, hope it helps someone else.
