Having issues starting a majority of QT-created apps
-
I'm sorry ahead of time if this is the improper forum for this - I'm not a developer and I've got no knowledge in developing QT apps, but I'm at the end of my rope and this seems to be the only centralized place on the internet to contact QT experts or those knowledgeable in it.
Basically, a few different programs are crashing and throwing out errors in my Windows Event Logs with the faulting module as something related with qt5. It's different between apps, I believe, but they're generally preceded by qt5. Off the top of my head, one is QT5core.dll, I'll have to check again for the others, if it is important.
Before my first reinstall, I ran just about every virus scan known to man alongside three different rootkit detectors with, predictably, no results.
The apps that it has affected so far - EAC (EasyAntiCheat) - I'm completely unable to start EasyAntiCheat, so any game that uses it is out of the question. This includes Hurtworld, Rust, among others.The HTC Vive installer crashes before it starts. Also pointing to a QT5core.dll fault.
ReVive, an overlay to add Oculus games to Steam VR, crashes before starting and fails to do what it needs to do. This one points to a different QT5 dll, but I can't remember it off of the top of my head.
Stellarium is also giving me issues. Usually it won't boot at all, but if it does, it gives me this error.
The same (or similar) to the others.
Steam VR, which is also built on QT, works, but the menu is buggy and often seems to display corrupted text instead of the actual menu items (for example, "options" would turn into "Menu_Vive_Options" or something similar).
Origin is crashing with the same error (even though it has worked in the past). When it doesn't crash outright, It's giving me this screen when I log in.
What I've done so far:
- Complete Windows format and reinstall (twice) as well as an in-place refresh (once).
- RAM Test (Memtest overnight)
- Prime95 CPU test (seven or so hours)
- Revert from safe, stable overclock to stock (You know, just in case)
- Multiple, exhaustive, virus scans, including Malwarebytes and a number of rootkit scans. Nothing at all. Of note, I haven't had a virus for over a decade, so this was just me being paranoid.
- Uninstalled, repaired, and installed a whole slew of runtimes
- Ran a chkdsk followed by an SFC scannow, followed by a DISM. No issues detected or repaired.
- Per-app troubleshooting and compatibility tests
- Changing the hard drive they're installed on. I've got a number of hard drives - I keep my gaming stuff separate from my OS. I doubt that would matter, considering a lot of people do this, but I was desperate.
- Selective "clean boot" with no non-windows services or startup apps running.
Somewhat related - what this guy and EKO, at the bottom of the thread, are encountering seem to be at least somewhat similar to some of the problems I'm running into.
Thanks ahead of time for absolutely anything. I've been working on this issue for what feels like a month straight and I'm about to tear my hair out.

Hi and welcome to devnet,
One thing you can try is to download the latest Qt 5.7 using the online installer and then replace the .dlls in one of these application folder with the one from that installed Qt (also the plugin, platform and other folders containing Qt related .dlls).
Hope it help keeps your hair safe.

Thanks so much for the attempt, but in an awful turn of events, I can't even install QT - the installer had odd graphical glitches (Checkboxes had no text), and then it crashed when I tried to install it.
Nothing is safe from this bug I'm having, much less my hair, haha.
No idea if this will help, but very typically, if a QT app doesn't crash outright, I see some weird corruption in the menu items.
An example of this - Origin's title bar reads "application_name". Steam's VR interface will often totally go wonky, with every single item being a long descriptor like that instead of what is supposed to be there. Also, whole windows are sometimes completely transparent.

Which version of Windows are you running ?
-
Windows 10, 64 bit, Version 1607, build 14383.187. That said, it's persisted for quite a while. I can't pinpoint exactly when it started, but I, at the very least, had it before the Windows 10 Anniversary Update.
My first real run-in with the bug, I believe, was early June of this year upon attempting to get EasyAntiCheat working, although it's possible I had issues with it before and simply didn't connect the dots.
-
Are you using the nVidia driver or the one from Windows ?
-
Newest from Nvidia (which happens to be WHQL, I believe). Installed completely fresh with DDU. Not sure if it matters anyway - I removed my GPU to test and still came up with the issue using integrated graphics alone.
I was able to get QT installed, as far as I could tell, in Ubuntu Live running from a USB stick, but I was getting errors along the way. You can see a crappy video I took with my phone of it here. Not sure if that's just a quirk in Ubuntu running off of a USB, or if it's a continuation of the issue I'm having with my PC. It seems as if other people are having those same errors on other distros, so I assume it's just a quirk from running it via USB.
After I pushed through all of those errors, i was able to start QT on the live USB.

Huh, I looked at your video, lots of pain indeed. But if you can compile and consistently run some Qt examples on the Ubuntu stick, that would mean Windows is a bit loose.
I'm no hardware guy, but you tested the processor and RAM. And now you've also tested without the GTX970 and still Windows 10 glitches out :-(
Is it a Skylake processor? Some of these have issues with sleep and Intel's SpeedStep. Try disabling SpeedStep and advanced sleep modes in your BIOS. Also disable sleep in Windows. Just guessing :-)

Nope, Ivy Bridge - i5-3570k. I think I've disabled speedstep regardless, but I'll take a look. Can't hurt, at least. Thanks for the attempt!

Ivy Bridge - i5-3570k
I have that exact processor (without overclocking though) and I haven't observed anything suspicious about it.

Yeah, same. It's actually worked fine for me for some time. Suddenly, out of the blue and without changing anything, I'm getting errors and crashes all over the place. It's infuriating.
@hskoglund said in Having issues starting a majority of QT-created apps:
Ivy Bridge, then you should have a Turbo Boost setting in your BIOS? Try disable that also.
Sure do, it's actually what I was using to overclock. I had a slight overclock going for some time with the turbo boost numbers. Tested stable and cool for the longest time. That said, I've already reverted it to stock for test. I'll try dropping turbo boost if there's a setting.
Update: Went as far as going with a fixed ratio, turned off speedstep completely, turned off turboboost. No dice.

Any chance of having that since the Windows 10th Anniversary update ?

I'm with you on that. I'd always suspect software before hardware ... especially the video drivers ... and of course Windows itself ...

Unfortunately, at least some of the issues preceded the Windows 10 Anniversary update. The Vive setup was crashing as early as July 28th, when I got it, and EasyAntiCheat was crashing even before that (I posted about it looking for help on the Steam forums as early as June 4).
I can't pinpoint when Origin started crashing on me, but I suspect it was relatively recently. I can say that the last game I played on it was about seven months ago, so there's a possibility it has been messed up for a while.
I tried rolling back to 362 drivers, from March, for my GPU with no luck. I can try rolling back further, but I can't imagine others with the same GPU/drivers not reporting a similar issue at some point.
I'm honestly not super far from demoting this stupid computer to media center and building another one, although I'm fairly certain my head would explode if the problems persisted after a new Mobo/CPU/GPU.
That said, I'd be ecstatic if we were able to find a fix.

Hmm, perhaps it's time for some slight surgery (not on you but on your PC :):
if you have 2 RAM memory sticks, swap them.Was going to try that next, @hskoglund , even though they passed memtest, I figure it can't hurt to swap them, change channels, and remove one and then the other, just in case. I'm going to try that in a bit. Might have to head out for a job really quick for the time being, but I really, really appreciate all of the help you people are offering up.

In the same kind of idea, did you try to change the PCI slot in which you put the graphic card ?
