Anyone seen this before (desktop screenshot): https://iyt2pw.dm2301.livefilestore.com/y2pHbIVh7YI83KTddMt7zhCdJnnqt0M0VbEhgRwWKgzuHhN7fnc9WlKbxWYtwvX0AEv02ORuXalbTDZLPzO5hdxCJuYYdrptY5NvYxspmsE66U/win8_1-taskbar-glitch.jpg?psid=1
Basically, when I start a program e.g. IE11, the task bar at the bottom, which is set to auto-hide, partially shows with just a few pixels wide line from it showing, until I mouse down to it then the whole task bar appears. This has happened on several Windows 8.1/2012 R2 installs on this machine, which has a 3930K, 16GBs RAM, EVGA GTX 780 Classified, and Samsung 840 Pro SSD. All I have installed, since I just did a re-install to switch back to 8.1 from 2012 R2, is Visual Studio 2013 and a game (BF4). Using latest GPU drivers (337.88), although it never seems to make a difference which ones I use since it's always happened in 8.1/2012 R2. Been living with it since it's not a big deal, but I figured someone else would have seen it by now and MS would fix it in a patch, but nope. Turning off auto-hide of taskbar fixes it of course, but I like the extra vertical room since this is just a 1680x1050 monitor.
Minor edit: 16GBs, not 12GBs, of RAM.

I've never seen that before and I have worked on a variety of 8.1 machines with both AMD and Nvidia cards (and lots using Intel integrated video). Is it only happening on IE? I use auto-hide on my machine and it doesn't do that ever, even with IE. You have all windows updates applied? Even the 'optional' ones? And are the drivers from EVGA or straight from Nvidia?

I'm using drivers from NVidia.com, I have every update installed including optional (except the bing bar/desktop items). It happens any time I launch a program. System is otherwise 100% stable, no BSODs ever or unexpected app crashes.
Edit: OK, just figured something out. it only seems to happen when my second monitor (which is actually listed as monitor #1 in Windows, connected via HDMI), a HDTV and my primary monitor (Dell 2209WA connected via DVI) are set to 'extend' mode, with windows set to display only on my Dell 2209WA, the task bar doesn't glitch when launching programs. Don't suppose you've tried taskbar auto-hide with two monitors? Probably a GPU driver problem, I guess I should post the issue on NVidia's forums. |

Yeah and they are identical Asus 26" monitors but one uses HDMI out (to an HDMI to DVI cable) and the other is the DVI output. I run dual monitor on almost all the computers at the office and none have that problem. Of course, none use an actual HDTV as a monitor, just matched desktop monitors, mostly. Some use slightly varied monitors, like 2 different models of dell or whatever.

Weird, it's like it's hiding, but not shrinking down? I've never seen that. Have you done any of those idiotic Windows tweaks in an attempt to "optimize" the OS?

I've done some tweaks, but it happens as soon as I get finished installing updates and gpu drivers before I touch any thing else, and the tweaks are pretty basic, things like bcdedit /set disabledynamictick yes, bcdedit /set useplatformclock true, disable autoplay, and set power profile to max performance, not stupid stuff like deleting system files or installing hacked themes. |

Quote: bcdedit /set disabledynamictick yes, bcdedit /set useplatformclock true Why would you do that? |

Yeah, you did a stupid thing.
Those options are for debugging purposes. Disabling the dynamic tick increases CPU usage and lowers performance. Code: bcdedit /set disabledynamictick no, bcdedit /set useplatformclock false Run that and reboot. Even if it doesn't solve the issue, don't touch em. I do know that way back at the release of Windows 8, disabledynamictick had a use in fixing an issue on MacBooks until Apple released newer drivers. Disabling autoplay or changing power profiles is fine, but messing with bcdedit when you don't have to? That falls into idiotic Windows tweaks. |

I enjoy high bit rate movies, and hate any glitching. platformclock, I'm not %100 about but I would think the higher precision clock would be better. Anyway, it wasn't these, I did a fresh install since I hadn't installed anything any way, as soon as I first logged in, I just installed the graphics drivers, enabled auto-hide for task bar and the glitch immediately happened. Anyways why argue with me about it or express exaggerated opinions on them, they have nothing to do with the topic. |

aggressiva, this won't be of much practical use to you, but I've been experiencing some taskbar glitches as well recently. I'm on Windows 7 with the taskbar set to always show, and while 95% of the time it works fine, the other 5% it will always-show the taskbar even while I'm in a full-screen app such as VLC. Sometimes it goes away if I press the Windows key twice (to show and then dismiss the Start menu), sometimes it doesn't.
So yeah. I know that feel, bro. |

Well if it happens on a fresh install I would say you have a hardware problem. Do you have a different video card to try? Or can you use the on-board video?

That thought crossed my mind, but I literally get not even one other error. And I play several high end 3D games and tried some demos on this box. Unfortunately I just parted with my last secondary video card, so I'll have to go buy a cheap one I guess. Just wanted to know if someone else saw this before I did all that. Apteris: hmm, sounds kind of similar, cause I seem to have that issue as well, it's just that the task bar doesn't display the bottom part of itself all the way when it goes into always-show mode.. |
|
I am having the same issue with my 780 (I think its card related myself)
Did you get a fix? My start menu literally looks the same as yours from time to time. |
|
Never found a fix, just learned to live with it and disable my second screen when not using it which fixes the glitch temporarily.

Quote: dynamictick disabled lowers DPC latency That's not true. It lowers DPC latency as measured by stupid DPC latency measurement programs. Most DPCs are not timed and happen as soon as they need to happen. |

Most DPCs are not timed and happen as soon as they need to happen. I've seen people who have fixed video/audio playback issues by lowering DPC latency as measured by these programs. Any ways, what does it hurt, a few more watts per hour on my desktop PC perhaps? |

It is plainly obvious that this defect is not a "hardware problem" in any meaningful sense. Hardware problems do not manifest in this way. It is most likely a driver defect of some kind. |

Looks like the august 12th update fixed it. Can't get it to glitch any more. hooray.
