affects even factory setting's cube if keyframed.

Can't recreate that but I'm also not sure what the error is. Please attach a .blend for us and give precise steps to reproduce.
@JulianEisel this simple cube animation should move across the screen when the play button is pressed. in the latest build it doesn't move and the timeline is not updated, even though the red stop anim player button is displayed at the top of the 3d window.
untitled.blend
the jump to first and last frame buttons are still working, and dragging the timeline works, so it appears it's only the play button is broken.
Hmm, still can't recreate here. Also not using the play button. It might be a draw buffer problem so could you play a bit with the "Window Draw Method" menu in the UserPrefs to see if that helps?
i just went through all the options on the systems tab and couldn't get the animation to play. previous builds work fine, so it's something about the latest one.
weird, i got it working temporally by tapping either the ctrl or shift keys. the animation would then play and loop. but if i stopped the animation and started it again. it didn't play, until i pressed one of those keys.
i've never seen this type of bug before.

Can you try loading factory settings
Also thinking sticky keys
@Blendify i've just tested with factory settings and no project file.
just pressing the play button for the time line to update. and it only does consistently if using shift or ctrl keys, all other keys appear to update for a split second and then freeze the playback.
Like I said I think this is sticky keys since it broke after that was committed
@Blendify, how could you know that? There were 21 commits during that time, and plenty of them were animation related. More important to know would be if you can recreate this.
Doesn't really make sense to have this assigned to me as long as I can't even recreate.
guys, just to clarify, i don't personally use any ease of access features in win7.
so i assume blender has some code to detect if windows is using sticky keys?
Added subscriber: @mont29
Cannot reproduce either.
@rattyredemption sticky keys are a new feature in Blender, you can try disabling it (UserPreferences, Input, set Click Timeout to 0) - and please also check the latest build from our buildbot, @JulianEisel made some fixes yesterday…
Not quite sure this would be sticky keys anyway… Can you also try to change synch settings in timeline (you are using No Sync, please try with frame dropping or AV sync).
Re stickies - see here .
I worked on something animation related yesterday and I also observed a weird behaviour: When I set a keyframe the keyframed object always jumped back to it's initial position so it didn't animate as well. I found out that this only happended if a Graph Editor is open. Not sure if that's the same thing, but I can test a bit more later today.
good news,
a1c2b1ais working as far as i can tell.i didn't change any of my settings. so what ever you did to the code apparently fixed this bug.
update, av sync is producing very erratic stuttering in the above build. i don't normally use it, but it doesn't behave the same as no sync or frame dropping.
in the
a1c2b1abuild, i just noticed something odd when setting click timeout to 0.the tab and z keys stopped working in the 3d view.
other keys appear to work fine, but i couldn't toggle into mesh edit mode, or toggle between wireframe and solid draw modes using shortcut keys. i could still do so with the mouse and relevant buttons.
setting the click timeout back to 250 then worked with those keys. this is with factory settings.
@rattyredemption, this is to be expected, Tab and Z got some hardcoded changes so that the Pie Add-on can use them to create stickies. Unfortunately it currently isn't possible for Add-ons to change shortcuts so they had to be hardcoded (spacebar won't work as well btw).
Setting the Click Timeout means you always call the operator that is assigned to Key-Hold which is nothing in your case so nothing happens of course. The reason why you should change the Click Timeout to 0 is to see if that resolves the issue.
Changed status from 'Open' to: 'Resolved'
But apart from that it looks like the issue got fixed, so closing this as Resolved.
@JulianEisel i think i understand all that. cool.
does it matter what the click timeout is set at if it's above 0?
The higher you set it the longer you've got time until holding the key does nothing or if you've something assigned to Hold, until it calls the operator assigned to Hold ;) I set the default to 250ms which seems fine, feel free to set it higher.
understood, thanks.
