PDN 4.0 crashes on startup - HA issue?


Recommended Posts

Yesterday I installed PDN 4.0 on my desktop (x64) and laptop (x86), both Win7. It works great on the desktop, but not at all on the laptop.

 

The laptop is an ASUS, 2GB RAM, with a dual graphics card built-in: low-level ASUS software will autoswitch between standard Intel for low-energy situations, and better Nvidia for graphics-intensive work.

 

PDN 3.5.11 worked fine here. PDN 4.0 did install without problems. But every time I try to actually start PDN 4.0 on this laptop, the borders of the main PDN window and the four tool windows will appear for a split-second on screen, and then before these outlined windows are even filled in, PDN crashes right away (I mailed a report as requested).

 

The crash reports all note PDN addressing inaccessible memory, and suggest "corrupt memory" as a possible cause. I can't believe that, afaik there's nothing wrong with the laptop's memory. Just to make sure I ran the Windows Memory Check tool -- it reports no errors at all. Nor do I have any "weird" software running that would mess up memory allocations.

 

My own hunch is rather there's some kind of hardware acceleration error going on here, possibly caused by the laptop's dual-graphics-card setup. Problem is, if PDN 4.0 is using HA by default (even it has an option somewhere to switch that off) I cannot change that setting, because PDN keeps crashing before I can get to any menu.

 

Still I'd like to find out if this may indeed be the issue here. So my question is: does PDN 4.0 use HA by default when it starts up? And if so, is there a way to force PDN to start up without using any kind of hardware acceleration? By commandline option perhaps? Or by changing some registry entry? INI file?

 

Thanks for any helpful idea!

Below is the latest crash report, identical crash. Before replicating the crash I made a new, clean install of PDN 4.0 instead of upgrading 3.5, so this eliminates any potential problems with old plugins that 3.5 had in its Effects directory. I also checked the laptop for .NET 4.5 (is installed) and just to make sure, I let Microsoft's own .NET Framework Repair Tool make a full run. To eliminate any other factors, I quit nearly all other software that ran in the background before starting PDN.

 

As for the dual-graphics-card setup, the laptop was on AC, not on battery while replicating the crash, so it was using the Nvidia. From the crash report it looks like PDN in this situation saw just the Nvidia, no Intel graphics, so probably the dual-graphics-card thing is not the issue like I thought first.

First, please do the standard troubleshooting things: get all your Windows Updates and make sure all of your drivers are up-to-date. This looks like it's caused by a serious problem in your video card driver -- the crash is internal to Direct2D, and not caused by Paint.NET.

 

I'm working on a fix that will automatically disable hardware acceleration when this happens.

 

For now, you can disable hardware acceleration by editing the registry. Create a string value in HKEY_CURRENT_USER \ Software \ Paint.NET called "UI/EnableHardwareAcceleration" and set it equal to "False" (without quotes).

 

Alternately, download the attached ZIP which has a REG that you can just double click on and it'll do that for you automatically.

 

Here's what the .REG has inside of it:

Windows Registry Editor Version 5.00
 
[HKEY_CURRENT_USER\Software\Paint.NET]
"UI/EnableHardwareAcceleration"="False"

PDN4_DisableHardwareAcceleration.zip

Thanks people for trying to help! But...

 

(1) I cannot believe something is wrong with my laptop's memory. As said before, I ran the memtest tool which found no errors. Besides, if something was wrong with my RAM, wouldn't this cause problems with other memory-intensive programs as well? All other software runs without any problem of this kind...

 

(2) I successfully merged the registry line that switches off hardware acceleration. Unfortunately, after having made this change, PDN 4.0 still keeps crashing in exactly the same way, right after starting it up, with its window frames already visible but before the windows have been filled in.

 

So, I'm afraid the problem has not been solved.

Try updating your video card driver.

I didn't say something was wrong with your laptop's memory. I said the video card's driver is buggy. Big difference!

 

Can you please post the new crash log?

Dear Rick,

 

thanks for giving this your attention (btw my memory remark was not commenting to you but to the previous poster). The crashing problem has been solved now, though there still appears to be a strange HA problem.

 

I downloaded the correct Nvidia driver installer software and just to make sure, I had it make a clean install instead of an upgrade. Your idea was right: PDN 4.0 now starts without crashing!

 

But, when hardware acceleration is used, there still is a weird problem: trail-like artifacts. Like, when you select the paint brush and then just move the crosshair pointer across the screen (without pressing the left mouse button to actually draw) it will leave a kind of irregularly dotted black trail everywhere you move the pointer, both within the picture and outside the image canvas.

 

This weird behavior does not happen if I switch off PDN hardware acceleration in the registry.

 

The Nvidia control panel has an option that lets the user switch all kinds of functions on or off, individually for any specific program or process. Do I need to adjust some of the default settings specifically for PDN, to make hardware acceleration work properly?

 

Thanks once again! Henk

The artifacts you're seeing are another known issue with various video cards. I'm not even sure if it's fixable -- it may be a serious bug in Direct2D.

 

What happens when you switch to something like a selection tool and draw a selection? Do you still get artifacts?

 

I had someone report that they got all the trails and stuff when they start up (and the paintbrush tool is active), but they switched to another tool and it went away ... and I think they even created a new image and the artifacts were gone then too.

 

If you can find some situation where the artifacts aren't there, that'll help.

BTW, this should be fixed since 4.0.1 (the latest version is now 4.0.3).
