Process Hacker 2 acts veery strange after some time

[TETYYS]

After updating to 2.38 after some time it happens to act really strange before just not responding.

• Tray icons crash, just displays transparent square
• Scrolling the process list doesn't display processes, it just duplicates existing rendered graphics
• Displays scaled / distorted current rendered object artifacts on monitor (not only on PH window, also affects second monitor), here's part of bambalooza I've managed to snap http://i.imgur.com/7IO23cv.png

Have you tried disabling plugins using the Options window and unticking "Enable plugins" on the general tab?

[TETYYS]

I've disabled some plugins and now I'm waiting because I didn't want to set up my columns again after disabling plugins. I'll backup settings.xml and disable all of them.

[TETYYS]

1h in, no problems, enabled plugins: .NET Tools, Average CPU, Boot Entries Plugin, Debug View, DNS Cache Viewer, Global Atom Table, Hexadecimal PID, Online Checks, Running Object Table, UMDFHost Process Plugin, Update Checker. Waiting...

[dmex]

Why do you have UMDFHost Process Plugin? That was integrated with PH ages ago, you can remove it.

[TETYYS]

lmao, enabled Windows Explorer, WaitChainPlugin, UserNotes. Waiting...

[TETYYS]

Everything seems fine, + Emergency, Extended Notifications, Extended Services, Extended Tools, Firewall Monitor

[dmex]

Remove Firewall Monitor... It has some known issues with GDI handles and is very likely causing the problem.

[TETYYS]

I'll keep the PH running, see if it crashes

Enabled all plugins and it doesn't crash so far... Could it be UMDF?

[TETYYS]

This time it crashed programmatically immediately when I tried to move CPU Average (60) column through Choose columns... menu because when I dragged it, nothing happened. But I don't think it's the cause because when the bug happens, all GUI just keeps not responding, acts weirdly. Crash.png

Where did you get the extra plugins from? Make sure you're compiling them against the latest SDK.

[VictorVG]

On Win7 SP1 x64 and PH v2.38/2.39 this problem not exists. I use AtomTable, AvgCpu, BootEntries, DbgView, DnsCache, DotNetTools, ExtendedNotifications, ExtendedServices, ExtendedTools, FirewallMonitor, HardwareDevices, HexPid, NetExtras, NetworkTools, NvGpuPlugin, OnlineChecks, PerfMonPlugin, ROTViewer, SbieSupport, SecurityExplorer, ServiceBackupRestore, SetCritical, TaskbarExt, ToolStatus, Updater, UserNotes, WaitChain, WindowExplorer plugins..

[TETYYS]

I got extra plugins from latest Git repo and compiled with latest SDK. I'll disable my plugins just to make sure and keep the PH running for a couple of hours.

Crashes without my plugins, I'll go one by one, this time ToolStatus, -Window Explorer, -User Notes, -Taskbar Extensions, -.NET Tools, -Extended Notifications, -Extended Services, -Extended Tools, -Hook Tools (Colin), -Hardware Devices, -Firewall Monitor, Same Win as @VictorVG

[wj32]

No clear instructions to reproduce... I constantly run PH for hours/days without restarting and it seems fine to me :)

Same here.

[TETYYS]

That was the case for me too before update, but now, something's strange happening.. :cry: This is how process properties window looks like when the bug is in action

[dmex]

I've seen similar things when the desktop GDI resources are exhausted or something is using GDI incorrectly

[TETYYS]

Yeah, it just looks like objects have been free'd or something

Seems fine with this combination: +ToolStatus, +Window Explorer, +User Notes, +Taskbar Extensions, +.NET Tools, +Extended Notifications, +Extended Services, +Extended Tools, +Hook Tools (Colin), +Hardware Devices.

[TETYYS]

Is this related? https://github.com/processhacker2/processhacker2/issues/21

[wj32]

@TETYYS No

[wj32]

It looks like something is deleting the font object that's being used by the standard controls.

[dmex]

I think this was caused by a bug in the way Taskbar Extensions was getting it's GDI handle for drawing the taskbar graphs every update interval (e.g. every second it was using the GDI handle from the main PH window instead of the desktop screen handle).

I've made some changes that should fix the issue (if it's indeed the cause)... On a side note, you shouldn't be using any Plugin-Extra plugins, the whole reason they're not included in PH and the main reason we don't provide binaries is because they have major issues in one way or another and very likely to have major bugs.

[TETYYS]

This was indeed caused by Firewall Monitor plugin.

[dmex]

I've disabled process icons in the Firewall Monitor plugin...
