Hi, in the last few days my SP3 has had quite a few bouts of extreme unresponsiveness.
When it occurs the touchpad lags by 3-10 seconds, and screen touch is also conked out.
It tends to start in chrome or firefox (but that's also where I spend a lot of time so may not be meaningful), and it seems to choke all apps including File Explorer while it's happening.
App switching via Alt-tab seems perfectly normal though, so the window manager process it unaffected.
After 5 or 10 minutes it comes right and then operates fine until it does it again hours later.
The strangest thing is that it makes a weird chirp/plop sort of sound from the speakers when using the touchpad or touchscreen in this state - it's like a proper system sound, but I have the sound scheme set to none, and it doesn't seem to match any of the standard windows sounds.
I can't find anything corresponding in the event logs: has anyone had a similar experience, or have advice to offer?
Edit : Just after posting I had it hit again, and at this stage I can trigger it 100% reliably with a two-finger scroll on the touchpad - in Chrome, Firefox, Control Panel (Old Windows style), Libreoffice, Komodo Edit. But NOT in Edge, IE, Notepad++.
Touchscreen scrolling in everything is fine, as is PageUp/Dn via keyboard, but right at this moment in time I can trigger a total cursor freeze (complete with chirping noise) in any of the apps listed in bold above any time I try touchpad scrolling.
I know apps are built with different toolkits, and apart from Control Panel I think many of the problem apps might use GTK, but have worked fine until the last week.
