QWT

[Drew White]

Hi folks,

Is there a leak in the QWT QGA.EXE that means it jsut keeps consuming CPU resources?

It uses between 10% and 60% of the CPUs that I assign to the system, slowing the whole thing down.

It's not like I'm using 3D graphics or anything advanced. Just simple rendering things.

Also...

System Tray is not respected into Qubes itself, even under a sub-menu item in the system tray for that one guest.

Is there any way that this could be implemented please? If I minimise something to the system tray I can no longer access it. Task Bar is fine, but System Tray is not.

Have I not set something up that should be?
Is there something that is required for it to be done that I have not got installed?

What is it that you would require to be able to look into this issue?

Sincerely,
Drew.

I remember omeg mentioning somewhere that the mouse emulation code is cpu heavy and might be the culprit behind heavy cpu usage.

I never had/knew about this issue, sounds like an odd bug.
How powerful is your CPU? Percentages are arbitrary numbers without something to compare the percentage with. For example if you got an Intel i5 4th generation, or AMD A6, or something, it might be more easy to relate with the percentages.
If you got a powerful machine, and it uses that much percentages, it gives a different view, compared to, say a weaker machine.

I might not be able to provide a fix, but the more information you provide, the easier it gets for those who maybe can provide one.

There is also a chance that this is fixed in the upcoming Qubes 4.

It is odd, because I never had this issue with earlier versions of the tools like I have on my PC. my PC uses way less resources for it, even in Seamless Mode.

It's an i7. I'll have to get the full specs for you.
I have 2 threads with 2 GB RAM assigned to the Windows 7 Guest.
FYI, it is NOT running in Seamless Mode. That's just standard.

What more information can I provide?

Qubes 4 will NOT run on my hardware. Qubes 4 REQUIRES things that my hardware does NOT have.

My PC is a Hex Core (Hyper Threaded) Xeon with 24 GB RAM.
Not something I need to upgrade any time soon.

Is Qubes 4 still built around using Python as the middle-man ? Or has it been upgraded to something less resource intensive?
