Description Peter Hutterer 2009-09-16 23:13:33 UTC

Core motion events include integers only, we should skip those that don't change (only in subpixel areas). Same applies to XI1 events.

Testcase:
move the mouse over xev, then set extremely high deceleration
xinput --set-prop "<device name>" "Device Accel Constant Deceleration" 1000, then move the mouse around. the cursor won't move much, but loads of motion events with the same coordinates are sent to the client.

I don't know what fixed it but I haven't seen this for a few days now (before that it was every few minutes).

Comment 2 Peter Hutterer 2009-09-27 19:59:19 UTC

Not happening for 1.7.0, punting to 1.7.1

Comment 3 Peter Hutterer 2009-10-12 21:05:11 UTC

Just noticed this, comment #1 was supposed to go to Bug 24011. The core motion events are still an issue.

Comment 4 Peter Hutterer 2010-07-14 21:20:04 UTC

feature request bug. this should not hold up any releases.

Comment 5 Peter Hutterer 2016-11-28 04:39:43 UTC

This is a mass change of bugs. Bugs assigned to me that haven't been updated in the last 3 years are closed as WONTFIX, because, well, let's at least be honest about it.

Please do not re-open unless you have a really good reason to do so (e.g. you're fixing it yourself). If it hasn't been fixed in the last 3 years, it probably won't be fixed anytime soon either. Sorry.
