Minimize animation flickr when for maximized apps

[Owais Lone]

If an app is maximized in Unity, the minimize animations does not render smoothly. It produces flickr as if the title bar is re-drawn at different positions until it it reaches the icon in the launcher. It really really looks ugly. I'm using Intel 950GM

see the video in comment#10

Looks like it working fine in 3.6.6 I'll test more for some time and then update the report

[Owais Lone (loneowais)]

Just restarted and the problem resurfaced again. It seems to render smoothly when using autohide on launcher BTW.

isnt't it specific to windows maximized in unity i.e. the one'e with their window controls in the panel.?

[Owais Lone (loneowais)]

yes, that's right.

[Omer Akram (om26er)]

The issue is on NVIDIA too.

[Omer Akram (om26er)]

Owais, with the latest version of unity and compiz in natty this issue seems to have solved for me but as it turns out unity stopped working for you. When you get it to work please try again to reproduce this bug.

[Owais Lone (loneowais)]

I got it to work again (partial upgrade due to some error on the filesystem). Anyways, the animation runs smooth now, just like for any other unmaximized window but it still leaves a trail of the title bar behind sometimes. The issue seems to pop up randomly, sometimes it works fine, sometimes it leaves behind ugly pictures of the title bar.

[Owais Lone (loneowais)]

It's still reproducible in Unity 3.8.6

[rfvuhbtg (rfvuhbtg)]

Also reproducible in Unity 3.8.14

I have slowed down the minimize animation to make the problem clearly visible.

If anyone fixes this bug they will get alot of love from me :)

[Omer Akram (om26er)]

Oh well it seems the latest update of Unity fixed this bug automagically :)

[Owais Lone (loneowais)]

Not at all. I can still reproduce this on Intel GPU.

[Omer Akram (om26er)]

I tried to reproduce it to every angle but Its fixed for me, I have
intel as well.

[Owais Lone (loneowais)]

Unfortunately, I'm still getting this with latest updates.

[bwat47 (bwat47)]

I can also still reproduce this on an intel gpu, on natty and oneric.

[Terence Sambo (arubislander)]

As can I, but only in Oneiric, using the nouveau drivers. I use the proprietary drivers on Natty, so that might be the reason I don't have the issue there.

[Owais Lone (loneowais)]

If I was Mark, I would add a special bug status "Super Critical" and assign it to this bug :D
This is so annoying, it makes the desktop look like crap.

[Omer Akram (om26er)]

>> If I was Mark, I would add a special bug status "Super Critical" and assign it to this bug :D

but I have never seen Mark setting status of a unity bug above High ;-)

[Omer Akram (om26er)]

Setting to a milestone so this bug can be tracked and maybe someone gets around to fixing it, this bug is not specific to any GPU it happens with all. and it looks BAD.

[Omer Akram (om26er)]

Assigned Robert if he might be interested, please feel free to un assign yourself if not
