firefox window suddenly resize to about 10x100 mm to upperleft screen corner

[Tora Kuat]

While browsing with Firefox, for UNKNOWN REASON, suddenly resize to about 10x100 mm aligned to upper left corner of the screen. Grabbing is not possible, resizing is possible using "Shift"+"Ctrl"+"Left Arrow" short cut.

In other instance it suddenly maximize to whole screen, the left side is behind the unity dash column and can not be accessed by mouse / cursor. Resizing using "Shift"+"Ctrl"+"Left Arrow" is possible. Back to "normal" from there.

What activities lead to this anormality is not clear to me.

This "bug" does not happens everytime. Since upgrade to Ubuntu 14.04 April 17, it happened 3 - 4 times.

This bug happens for me since fresh install on daily basis. I am experiencing it (Window suddenly vanishes into a fine strip, resizeable though, if you by luck detect the fine strip, OR Window just minimized into incomplete window (no correct header) the size of 10 x 100 mm).

I am experiencing it NOT ONLY with FireFox, but also Libre Office, Thunderbird windows.

I am experiencing it SEVERAL TIMES ON DAILY BASIS. It affects usability, when you work and the window just vanish. It is unimaginable if you make presentation in front of public and this thing happens on promoted Ubuntu.

I have not found out, what action leads to this bugs. I suspect something corrupt in windows management.

New Picture attached below, proofing the window suddenly minimize to 100 x 10 mm. However not yet be able to reproduce it on purpose. BUT is does happen a few times every day, and it is not good. Observed affecting LibreOffice Calc, Thunderbird, Firefox.

Compiz problem?

I update regulary (Software Update). Somehow, by today August 18, 2014, I do NOT see the problem any more (FireFox, Thunderbird and LibreOffice Windows suddenly minimize to 100 x 10 mm, without maximize, close, minimize, unmaximize buttons, and can not be dragged, only can be normalized by Windows manipulating short cut, such as "Ctrl" + "Up".

This bug can be considered SOLVED.

Thanks.

Regular updating. By September 6, 2014, error returns. At the end all this error reporting does not matter I guess. Just accept one's fate.

Status changed to 'Confirmed' because the bug affects multiple users.

[Thorsten (thorstenr-42)]

i am also affected by this bug. But its not only limited to firefox! It occours on all windows and also occured last month!

I can reproduce this behaviour in firefox by using ctrl-down to minimize the window. Bug also occurs on my laptop and pc.
