That helped. Further testing suggests my problem was OpenGL's fault. If it's enabled when I try to open or create something, the problem returns.

Hi, PIxelSprite!

Could you start DebugView before running Krita and send us the output?

This is what came up upon clicking new after enabling OpenGL (I edited out my name):

Hi everyone,

Just downloaded the new installer

Windows 8 - 64 bit (asus notebook s56c)
cpu intel core i7 3537U;
GPU nvidia geforce 740M (2 giga ram);
8 giga ram

I am unable to test this new build since I have tried to duplicate the same bug just mentioned by PixelSprite
In short:
1. I have opened an image (no problem at all: everything worked as expceted...).
2. *Afterwards*, I have enabled the OpenGl feature (to duplicate the bug).
3. I have tried to open another image (Krita crashed).
4. Now I can not try Krita anymore because there is no way to disable the OpenGl feature: I can not run Krita as far as the settings for this Opengl option...
I have even tried to open a "Custom Document" but Krita crashes as soon as I click ok (as a consequence, I am stuck...)

For me everything works just fine - new files, opening all projects. For now I didnt noticed any problems. Will let you know if I run into some. THANKS!

Krita "should" autodisable opengl if it notices a crash when creating the opengl canvas... But that's a bit hit and miss. If you remove

c:\Users\YOU\AppData\Local\krita
c:\Users\YOU\APpData\Roaming\krita
c:\Users\YOU\APpData\Roaming\.kde

(It depends a bit which directories are created, and I don't know what it depends on), then everything should be default again. For development builds, that's a good idea to do in any case.

The XP build by Ghevan is now also available:

http://heap.kogmbh.net/downloads/krita_ ... 7.8.29.msi

Note: you need all service packs! (And using XP is not recommended or endorsed...)

Hi everyone,

I have investigated a bit further the opengl issue with this latest installer.

More precisely, I have installed this new build (64 bit) on a different notebook:
- Windows 7 - home edition (64 bit)
- Cpu i7 2630 Qm
- Gpu geforce GT 540m CUDA 1gb
- Ram 8 gb

As usual, I have tested this build *before* enabling the opengl feature (everything worked as expected...)
Later on, as to duplicate this bug, I have enabled opengl again (standard options: NO change done).
As soon I have restarted Krita I have unleashed the hell once again

At present, Krita hangs up on Windows 7 - 64 bit as well.
In essence, it is not a Windows 8 problem as I have thought at first (since PixelSprite runs W8 as well).
I have even tried to delete the hidden folders suggested by Boud to NO avail (Users\App Data etc etc).

To recap, even on Windows 7 (64 bit), with an older Nvidia gpu, I can not find a way to go as long as to disable the opengl option (krita crashes as soon as I select no matter what document: custom, jpg etc).
As for me, the only solution is to uninstall this build and reinstall it without ever activating the opengl option ...

Hi everyone,

Actually, I have just succeeded in deleteting one more folder and now Krita (64 bit) runs again fine on Windows 7.

THANKS a lot indeed to Boud (just read his new post now...) for writing the complete list of all hidden folders to delete (before I have missed one of them...)

Silvio

By the way, I missed the deadline for 2.8, but for 2.9 or 3.0 -- I will have the settings menu show the configure krita dialog before a canvas is created. It already works in a branch

Hi Boud,

One more trial with an Asus netbook of a friend of mine
This one is NOT powerful enough to perform "seriuos" work (it is painfully slow) but it is a good candidate to test the opengl feature though

Asus netbook
Windows 7 - 64 bit (Home edition)
Cpu Atom(TM) D525 @1,80GHz
Gpu NVIDIA ION OPTIMUS
Ram 2 gb

As usual, after a first quick round of testing (which went fine) I have enabled the opengl option (bilinear filter as default) without changing anything else.
On this Asus netbook everything works as expected!
Later on, I have even tested the new High quality filter coded by Dmitry

To sum up:

1)
Asus notebook S56c (new computer)
Windows 8 - 64 bit (Home edition)
Cpu intel core i7 3537U
Gpu Nvidia geforce 740M (2 gb ram)
Ram 8 gb

Opengl does NOT work

2)
Asus notebook (3 years old)
Windows 7 - 64 bit (Home edition)
Cpu intel core i7 2630 Qm
Gpu Nvidia geforce GT 540M CUDA (1gb ram)
Ram 8 gb

Opengl does NOT work

3)
Asus netbook (3 years old)
Windows 7 - 64 bit (Home edition)
Cpu Atom(TM) D525 @1,80GHz
Gpu NVIDIA ION OPTIMUS
Ram 2 gb

Opengl DOES work as expected (I have even tested the new high quality filter)!

Best regards!

Silvio

I'll also point out that the sticking point seems to only be when opening or creating an image with OpenGL enabled. Otherwise, I thought OpenGL worked fine though I didn't test much (smooth painting, scaling, rotating). If you remember to disable it before switching to another file, Krita won't crash.

i have just tried the latest version. I encountered the bug where krita crashed on opening only on the helix(intelhd4000) and not on my desktop(gtx460). But i found that the problem was also gone from the helix if you enabled texture buffering.

So if you have a problem with krita crashing while opengl is enabled and opening or creating documents, try using texture buffers after enabling opengl the first time!

Hope it helps.

Didn't have time to test it on a project or something yet, but everything seems ok at first glance!

Same thing here, when OpenGL is enabled without texture buffering checked, Krita crashes on the next launch.
With both enabled, it launches just fine.

Otherwise things seem to be working great on my machine.

Krita is getting pretty nice to work with.
Thanks Developers!

Yes I've confirmed what PixelSprite, Panz and tparrott above mentioned. The problem is without buffered textures.

I also got an "Error during autosave. Partition full?" error, it has happened while I was drawing a stroke. Of course the partition isn't. And I can save the file normally.
