Pale Moon becomes sluggish if left open

Post by jooch » 2015-12-17, 20:44

Well the title sums it up, but here's what happens on my Manjaro x64 machine.

I start the system and open Pale Moon.
Browse a website (one tab, no flash).
Leave the computer running and return a day or two later.
When i return Pale Moon has become sluggish and even something simple as copying text to the clipboard almost locks up the browser.
Restart Pale Moon and everything is fine again.

Can't figure this one out, memory leak or something? I have tried it without Add ons, but the effect is the same.

Machine specs:
  • AMD Athlon 7750
    Uli Chipset
    Geforce 9400GT (Nvidia 340 drivers)
    Manjaro Openbox x86_64
    RAM 2GB, Swap 2GB
Cheers, Jooch

Have you checked memory consumption and CPU? I recommend htop for this. Not sure if the Openbox spin has it by default, but it might.

Tried reproducing it with hardware acceleration off?

Certainly! I always use htop, great tool. CPU is about 1 to 2 percent in use, but that's just background services.

Good suggestion on the hardware acceleration, i turned it off and currently running PM for 18 hours without errors

Interesting, I've only just started using Palemoon but so far I've not seen an issue while it has been left for 8+ hours on an AMD quad core with AMD graphics and 8gb main memory. I do have h/w acceleration set to on. I will keep an eye on it. I use Fedora X86-64.

It's likely an issue with it being poorly supported on your particular combination of OS/driver/hardware. Glad it got solved!

Still running the same sessions without errors, it is settled then i guess.
However, is there any way to trace this bug? Running PM from a terminal doesn't reveal anything...

Tracing these kinds of issues is extremely difficult. Unfortunately Linux-based operating systems are notoriously hard to deal with in terms of HWA and troubleshooting thereof because of the variety in not just kernel hardware support and drivers, but also the window manager layer and other abstracting layers between it and the browser... :/

Darn, i was afraid you would say that. I switched the Nvidia card for a Radeon 4870 i had laying around and set that up with the open source drivers. Usually that should play nice with any setting.

The issue is resolved in this setup, no more lagging or performance issues. Thus it is a problem with the propriety Nvidia driver and card combination.
Not that this solves the overall problem, but it's possibly useful information.

BTW: Is the acceleration part updated to Firefox's latest code? Or would that be version 25?

Neither. And we don't want Firefox's "latest code" either because it's terrible.
