Bug 69932

Watching the provided videos, the flicker is very apparent. The toolbar appearance is much worse in the 2nd video -- is that video demonstrating LO 4.1.1.2?

Testing on Ubuntu 12.04.3, I see icon repaint flicker whenever I resize the main window of LibreOffice in *both* LO 4.1.2.3 and LO 3.5.7.2. As such, changing 'regression' -> 'PossibleRegression' until we can get independent confirmation of a regression.

Pedro - Could you please provide a video of 3.6.7.2 showing the previous behavior? It would be great to see the before/after comparison so that we can identify and track down this regression.

Thanks

Joel -- Suggestions on flicker-related problems?

First thing I'd suggest is resetting the profile (unlikely to be the issue but always good to start with a fresh profile)

Next question - do you have a second system to test the same release in Xubuntu that does not have Nvidia driver? Perhaps some code cleanup on our side triggered a nvidia bug (not that hard to believe).

Lastly - PedroNGV - if we walked you through the steps to bibisect the bug would you be willing to do so? It would be very helpful to narrow down the range where things went wacky. If so, are you familiar with IRC at all? I'd be happy to walk you through the steps, they aren't that difficult but you do need about 20 gigs of free space and high speed net to download the daily bibisect package

No,

http://goo.gl/VeVkHg is LibO 4.0.1.2
http://goo.gl/4rkWJ is LibO 4.1.1.2

Despite everything, it is a little better in newer versions.

Yes, here it is: http://goo.gl/chu4d8 

Like you said, there is also some icon repaint flicker, but nothing to compare with versions 4.

Thank you very much!

Best regards,
Pedro

Hi Joel,

Whenever I test a new version, I purge LibO and delete the folder /.config/libreoffice.

Unfortunately, I only have another machine with Xubuntu, and is a laptop also with a nvidia graphic card. However, I have different versions of nvidia drivers - 319.49 on the desktop and 304.88 on the laptop.

The flicker is the same in both machines. It is even more noticeable on the laptop because it is a machine with less performance.

Yes, I would love to contribute, but I confess I do not know the process. If you can help me, I'm completely open!


> If so, are you familiar with IRC at all?

For a long time I do not use IRC, but if there is no alternative I can try to use IRC again.

Yes, I have these requirements.

Thank you very much Joel!

No worries about IRC :) You can do one of two things and I'll walk you through the steps:

1. Try on your own following the wiki: https://wiki.documentfoundation.org/QA/HowToBibisect

Make sure to use the daily build (not the 4.0 branch one, as it only goes through 4.0beta0 (unless you experienced the problem in 3.6.x)

or

2. Email me and we'll either setup a IRC time or go through email one step at a time.


Thanks so much for offering to help bibisect, that'll help tremendously

I went ahead and prioritized, changed version (Thanks to Pedro for doing a ton of work to narrow it down to 4.0.1.1 rc. 

My setup:
Ubuntu 13.04
LibreOffice 4.1.1.2 release

New (I actually was able to confirm after looking at the video a couple more times)
Trivial - no impact on ability to do professional work
Low - default is lowest but low because of regression


Thanks to Pedro's work I'm convinced it's a regression, Marking as ConfirmedRegression

Thanks Joel!

If this can help, I leave here two screencasts where we clearly observe the emergence of the problem in version 4.0.1.1:

- LibreOffice_4.0.0.3_Linux_x86_deb: http://goo.gl/yYj6MV 

- LibreOffice_4.0.1.1_Linux_x86_deb: http://goo.gl/SdGEFk 

Thank you very much!

Best regards,
Pedro

Removing comma from whiteboard (please use a space to delimit values in this field)

ConfirmedRegression (in whiteboard) -> 'regression' in Keywords.

(Ideally both tags would be Keywords or both live in the Whiteboard)

I experience the same kind of flicker on Ubuntu 12.04 x64 (kernel 3.5).

Using Libreoffice:
Version: 4.3.0.4
Build ID: 430m0(Build:4)

Furthermore, window controls like buttons flicker too...

Is LO 4.3.1 any better? If not experienced any flickering here with Ubuntu 14.04.

I'm still seeing some (small) flickering issues with 4.3.1.1 on Ubuntu 14.04:

For comparison, I do not see any flicker in the icons of Firefox 31 when I resize a browser window.
