SimpleScreenRecorder Blinking

[arkansawdave74]

Hello everyone. I'm getting some strange blinkings in my recordings on my "new" laptop and just wondering if anyone has seen it before, knows a fix, or can tell me a decent open source alternative. Thanks.

These flickers are generally due to low spec hardware. Try

1. Reducing fps of simplescreenrecorder. The video recorded might not look too good, maybe.
2. Try different software, I personally like obs-studio. But screen may still flicker
3. If nothing works, switch to lighter DE, maybe Cinnamon or xfce. Even gnome did help to remove these flickers in many cases.
4. Also see the following thread

Screen Flickering for CPU intensive tasks

Hi Just wanted to understand if I missed anything. I recently started using Garuda Linux (to be specific Arch) and was a full time Ubuntu user. Here the issue is when I am running my Virtual Machines or doing any CPU intensive tasks, my laptop screen flickers. I am not sure what is the issue, so after digging a little I found some post to disable "PSR" and setting idle state to '4' and did all that in grub but still have all these issues. Request you all to please assist and do let me know …

And btw,

@arkansawdave74

just wondering if anyone has seen it before,

Yeah, that's quite common issue.

[arkansawdave74]

@Naman

These flickers are generally due to low spec hardware.

Odd. I've got a quad 3rd gen i7 that scores 2700 in geekbench, but only intel 3rd gen graphics. Thanks for that informative answer. Definitely gives me some ideas of what to try.

And I bet it would be worse if this laptop had the 1080P display I thought it did when I ordered it.

Edit: Even at 30FPS it's blinking just as bad. I also messed with the encoding speed which hasn't helped.

Still have some ideas though.

[Naman]

@arkansawdave74

got a quad 3rd gen i7

It was launched in Q3 2012. And technology evolves too fast these days....

Intel® Core™ i7-3632QM Processor (6M Cache, up to 3.20 GHz) BGA - Product...

Btw, a little off topic, how much did you pay for it? And is this returnable??

[arkansawdave74]

@Naman

Yeah, but my other laptop that it's working fine in has a 2nd Gen i7. LOL.

@Naman

Btw, a little off topic, how much did you pay for it? And is this returnable??

I got it for $125 on ebay. Yes it's returnable, but it's hard to find this much processing power when you're as poor as I am.

I buy broken ones with no hard drive and fix them. This one the seller thought had a charging problem, but It's worked great with both the charger from my T440p and my universal one.

On the other hand, I damned near returned it when I found it didn't have the Nvidia GeForce 740M I thought it had.

[arkansawdave74]

LOL. I just realized, my CPU is pegged running hashcat in the background. Let me turn it off and test again at 30FPS.

Nope didn't help.

[Naman]

Maybe try this

Screen Flicker in Simple Screen Recorder

When I record with obs it flicker screen and my hardware is not that goo so it can provide 1908x1080 60fps recording so I use Simple screen recorder but it has same issue, and their is not a option of "Never" in vsync compostor in settings. what to do PC spec: i5 8th gen, 8gb ram, nvidia mx130

IIRC, it was quite effective on ivy bridge too.

Ok, that's understandable.

@Naman

Maybe try this

You know, I did a search in here and didn't see that one you linked. Thanks.

[Naman]

@arkansawdave74

Thanks

You're always welcome

So, I guess I should mark this thread solved now.

[arkansawdave74]

@Naman

So, I guess I should mark this thread solved now.

No Sir. I haven't fixed it yet. I'm currently trying to learn to switch the video driver from video-linux to video-modesetting. It's apparently a hard thing to find out. All the instructions I've found so far assume you-re trying to switch from intel proprietary drivers. Sudo pacman -R intel-xxxxx isn't going to work for me. I installed with free drivers since NO NVIDIA.. @Naman (or anyone really), you wouldn't happen to know the command to switch video drivers, would you? If you could just tell me which command/program that does it I could read some man and --help pages and figure it out. But it's a tough search.

[Naman]

Doesn't

sudo pacman -R xf86-video-intel

and reboot do the trick?

[arkansawdave74]

@Naman

Doesn't

sudo pacman -R xf86-video-intel

I'm currently using video-linux. I don't have proprietary drivers.

[Naman]

okk, I have no idea about these. I don't have intel now

Maybe some other can help...

[arkansawdave74]

I'll figure it out soon. I need to learn some search tricks.

I won't forget to come back and I'll put the command to switch to modesetting, since it's so hard to figure out, even if it doesn't fix it.

[arkansawdave74]

Because Garuda Settings Manager > Hardware Configuration didn't list video-intel I mistakenly assumed it wasn't installed because I didn't do the non-free driver installation. But, I saw my inxi said intel was the loaded driver and realized I was mistaken. It actually wouldn't uninstall by itself because of a dependency issue. I used

$ sudo pacman -R xf86-video-intel garuda-video-linux-config
$ reboot

Anyway, now modesetting is the loaded driver and simplescreenrecorder is working great now @ 60FPS. Thanks so much for your help @Naman!!
