Windows 10: Severe Input Lag and Other Issues Once a Full Screen App Has Run

I've been running Windows 10 for a little over a week now. At first everything was great, games ran fine, software all worked, and it was like I was still in Windows 7, only better.

Now all of a sudden today, when I'm in Star Wars: The Old Republic, running in Fullscreen Windowed mode, I get severe input lag along with some other bizarre issues, but only in certain software. For example, typing does nothing for a good 10-15 seconds in Skype, Word, and Sticky Notes, then all the typing appears at once.

I also get lag in right-click context menus appearing, and when they do appear, they're blank, with no text or buttons. If I click where I know certain commands would appear, it works correctly, so it seems to be a graphics issue. In addition, I have intermittent pauses when attempting to scroll through lists in things like Control Panel.

Yet other programs work perfectly fine (minus the context menu issue which is universal) including Google Chrome, in which I can type just fine. I can also type just fine in the Start Menu's search bar.

The bizarre thing is, even after shutting the game down, the lag persists indefinitely (for at least 15-20 minutes that I've tested) until I restart my computer.

The exact instant the lag appears, is when I click "Play" within the game itself, on a character, and it goes to the loading screen to load into a zone. The game engine can load just fine, all the way to the character selection (client is connected to server, graphics engine is loaded and running, no problems of any kind). Then the instant it starts to load a zone (probably connecting to chat servers, map servers, etc), it begins, and persists until restart.

Also keep in mind, this wasn't happening before today, even with the exact same game running, and the exact same system and operating system.

The game itself runs perfectly smoothly, 60 FPS, no input or typing lag. It's only Skype, Sticky Notes, and Word I can't type in, and context menus that have trouble, along with certain types of scrolling within Windows.

I've tried the Windows Troubleshooter, and it found no problems. I've also updated my graphics driver, and that had no effect either. The only thing I think has changed, was a Windows Update having installed.

Any ideas?

System is:
Gigabyte GA-MA785GMT-UD2H
Phenom II X4 965 (3.4 GHz)
Radeon HD 7850
12 GB RAM
1 TB main drive
Plenty of juice to run SWTOR.

Can Fullscreen optimization cause input lag?

Hello Patrick,

Full screen optimization will let users see a certain game displayed in windowed mode. This has caused issues for some in terms of running applications in full screen when playing games. Disabling it at times will help to increase smoothness and decrease
input lag in order to provide you with a better gaming experience.

Let us know if you have additional questions.

 

Windows 10 Anniversary Update bugs, the right-click pop up menu on any application shows a blank box unless I physically press the Print Screen button

I don't have that ASUS Suite on my computer. That sucks sorta. My problem shows itself when I use Scrivener. If i keep it open for a while then the keyboard lags, and if I keep it open for several hours, the keyboard lags in every other program EXCEPT
web browsers. I don't get it. But if I use the full screen editor in Scrivener there is no keyboard lag until I exit the full screen, then the keyboard lag shows. It makes no sense.

 

Curious update...

I did a remote control tech support session with a Microsoft tech.

Of course, while he was logged into my computer, I could not reproduce the issue. Everything worked fine.

The instant he logged off.... the issue began.

So something about him being logged in with LogMeIn, and using remote desktop control, prevented whatever this is, from going wrong.

 

Curiouser and curiouser...

It seems the problem is that once the game has run, the screen stops refreshing in Windows apps.

If I manually right-click the desktop and hit Refresh, things update just fine to where they should be. But until then, the screen just... doesn't refresh.

I noticed this and thought to try it, because my posts on Skype would appear instantly on my phone's screen, even when I typed them in on my computer. Only my computer's screen didn't update.

 

Alright. So now I have a workaround...

If I disable my graphics card in Device Manager, then re-enable it, it fixes the problem, until I run the game again. So definitely a graphics driver issue.

I'm gonna try uninstalling and reinstalling the graphics driver, and Catalyst Control Center.

 

Reinstalling drivers did not fix it. *Sad

 

And now it seems to have resolved itself, just as suddenly as it began. Not after a restart, not after any change in software, just... one minute it was borked, and the next it was working fine.
