There is flickering when navigating through the recent document list with a keyboard in the new Start center.
I see flickering too under Win7 64bit Version: 4.2.0.0.alpha1+ Build ID: 43cab408cdc9e3489113790d0990e50ca40f0adc TinderBox: Win-x86@47-TDF, Branch:master, Time: 2013-11-15_23:44:51 changing status to NEW. I add GUI expert to CC list.
Is this still happening for any of you with 4.2b2? I have never observed any such behavior. Maybe windows only? Or fixed already? Setting to NEEDINFO.
Of course it does.
Urmas which OS are you on? I've not seen nor heard of this happening on OS X so far.
Still wonder which OS this applies to. It has not and does not happen on OSX with 4.2.0.1. Setting OS to WIN since it's been confirmed on that platform.
tommy27 does this persist with 4.2.0.1?
I have installed Version: 4.2.1.0.0+ Build ID: 88cd9632e081f5839cf9fddf60cbff0c099e2968 TinderBox: Win-x86@42, Branch:libreoffice-4-2, Time: 2014-01-09_22:46:56 the problem is that I do not remember how to navigate through the recent document list with a keyboard... it seems arrow keys do not work...
Use tab until you arrive at the recent document list. Then arrows should work fine.
Confirmed on Win 7 with LibO 4.2.3.2
It's not limited to keyboard-navigation. It does apply to scrolling in the documents, too. The scroll bar also flickers. XP, v4.3 RC1
still flickering under Win7x64 using 4.4.0.0.alpha0+ Build ID: b9dca968c6fd0ab5ca140c65b0e54d153cd34986 TinderBox: Win-x86@42, Branch:master, Time: 2014-07-18_22:51:20
Confirmed on LibO 4.4.0.1 rc running under Windows 8.1 x64. Also, the interface should be more responsive when navigating with the mouse.
"flickering" do you mean the momentary effect while the screen is refreshed/redrawn on scrolling, mouse over, or keyboard movement of object with focus on the Start Center? Or as a manifestation of the digital video signal affecting the whole screen? On Windows 7 sp1, 64-bit en-US with Version: 4.4.0.0.beta2 Build ID: be92f32b8f21603a6b7a75dd645f7475bdee519d Locale: en_US and Version: 4.5.0.0.alpha0+ Build ID: 29c38bab7a69127c69f17c9a62b35faf68deb843 TinderBox: Win-x86@62-TDF, Branch:MASTER, Time: 2014-12-22_11:08:00 Locale: en_US I do see the first, and that is completely normal screen redraw of the Start Center panel, both with and without the Tools -> Options -> View "Use hardware acceleration". If this is the issue, please Resolve as Invalid. The later would mean there are GPU hardware and/or driver issues with you systems.

If this is the issue, please Resolve as Invalid. I think flickering, in any situation, cannot be normal. Is is a very annoying issue. And in these days when people are accostumed with using touch-screen devices which respond very quickly and without any graphical glitches, how can flickering be a "completely normal" thing? I don't agree.
There is NO flickering! Rather, as indicated, the entire GUI frame holding all widgets representing the recent documents list is being redrawn with each cursor movement of the focused object. That as distinct from a mouse-over activation which is only refreshing a single thumbnail view. @Kendy, before this is closed out of hand, is it possible to to adjust timing of the thumbnail view repaint to reduce the noticeable flash on redraw? Perhaps somehow fully buffer the frame first and then paint?
whether you call it flickering, flashing or redrawing, this issue is still present in LibO 4.4.3.2 and recent 5.1.0.0alpha
This issue needs a substantial rewrite so that it is possible to get rid of the flickering. The good news is that most of that has already happened, and we are bugfixing the rest (see the various commits mentioning 'rendercontext'). In the builds that have this enabled, start center is without flickering; we are now fixing Writer.
It became even worse, as the list is flickering even on scrolling now.
Due to the changed background colour of the Start Center (Version 5.0.0.5) to dark grey, the flickering is over again more obvious (scrollbar, keyboard). This is quite irritating and should be changed soon.

This is quite irritating and should be changed soon. Please let us know your OS, GPU and its driver details. And if you are working with Tools -> Options -> View: "Use OpenGL for all rendering" And if OpenGL is active, does "flickering" subside with it disabled? If that is the case, could be similar to bug 92708
OS: Win 7 Pro, 32 Bit GPU: NVIDIA GEForce 7950 GT Driver version according NVIDIA system control: 309.08 Driver version according OS: 9.18.13.908 "Use OpenGL for all rendering" is disabled. Option can't be enabled.

With option "Use OpenGl for all rendering" checked: (a) Scrolling with scroll bar: No more flickering, for me scrolling of thumbnails could be a bit smoother. (b) Scrolling with mouse wheel: No more flickering, for me scrolling of thumbnails could be considerably smoother. (c) Navigating with arrow keys: Works for me. With option "Use OpenGl for all rendering" unchecked: Flickering of thumbnails theirselves and scroll bar in all 3 cases. And: Changing the option will take effect only if LibreOffice is closed and opened again.
tested under Win8.1 x63 flickering is still present in LibO 5.0.3.1 even with "Use OpenGl for all rendering" checked. no more flickering with that option checked in LibO 5.1.0.0.alpha1+ (x64) Build ID: f173e148d8f2d0600fd50bee05e536932d529643-GL TinderBox: Win-x86_64@62-TDF, Branch:MASTER, Time: 2015-10-30_22:26:03 Locale: it-IT (it_IT) but if you uncheck that option the flickering will affect 5.1.x too my graphic card is ATI AMD Radeon(TM) R5 Graphics
Redraw of LibreOffice Start Center / Template Manager graphical elements on non-hardware accelerated systems has been improved about as far as can be done without major rework to simplify (and remove) visual features. What folks report as flicker, is precisely the element by element redraw of portions of the backingwindow canvas. OpenGL when available redraws smoothly, non-OpenGL rendering by GPU as controlled by OS drivers a bit less, and non-accelerated rendering by the CPU under OS graphics calls is noticeable as "flicker". This should probably be resolved WONTFIX, but alternative might be to disable thumbnail view features on the backingwindow when hardware acceleration is disabled -- presenting a static landing similar to pre-4.2 releases.

Poblem still exists in version 5.3.0.
I can confirm the flicker/flashing/redraw problem in 5.4.4 and 6.0 RC1 on two different Notebooks with Windows (Win81 32Bit / Win10 64Bit). It for sure is not a critical bug that should be addressed immediately, but it SHOULD be fixed in my opinion. And it doesn't make any difference if I use Classic Rendering or OpenGL, it flickers in all cases.

The bug is still there in 6.2.4. Btw. the headline is misleading, the flicker also happens with hardware acceleration enabled, at least as we talk about classic rendering. No flicker in OpenGl mode (seems I need to give OpenGL another shot, it seems to be improved since I testet it the last time...)
Ahh, im stupid, meant 6.1.4 of course :/ So again: The bug is still there in 6.1.4.2. Btw. the headline is misleading, the flicker also happens with hardware acceleration enabled, at least as we talk about classic rendering. No flicker in OpenGl mode (seems I need to give OpenGL another shot, it seems to be improved since I testet it the last time...)

If you verify the fix: make sure that your recent document list is long enough: I had 25 thumbnails in the start center and then the before/after difference with the Linux gen backend was obvious. Having just e.g. 3 thumbnails is not flickering even without the fix. (I haven't tested Windows with a small amount of thumbnails.)
Verified flickering is gone in 6.4 (I am able to see the problem with 6.3.0)! Thanks a lot.

Sorry, I need to reopen this, it turns out that my fix resulted in the much more problematic bug 127211, and I don't expect to have a fix for that in the near future. Hopefully the next person will be more successful. :-)
