Has it always happened? Sometimes recently installed programs try to access some service that a program you're currently in is using especially if they I put a background process in like an auto updater and other bullshit.

Try killing off everything you don't need to see if it's a confliction. Exit dropbox, web browsers, bluetooth, etc etc down to the bare bones if you have to.

Another possibility is wireless conflictions. Are you by chance using a wacom wireless and/or wireless mouse? Thats a recorded problem with that combo.

Also if you have regular wired gear your mouse may have an issue where it thinks the user is making motion when it's just sitting there which can screw with wacom input, see if having just one device attached helps.

It seemed to start happening once I had defined some more complex custom brushes. But it happens even when I'm not using those brushes... >_>

Eh, maybe I screwed up the config somehow? I guess I should reinstall Clip Studio and see what happens.

I suppose you could try killing those brushes first and giving it a go, but yeah a reinstall might clear up everything bruh

Your machine may have been compromised and made part of someone's botnet. Or you have the windows 10 bugware that microsoft put out as high priority updates to earlier versions of windows.

The pointer is freezing up just in this one application, not system-wide, so I don't think it's a system-wide problem.

Do a three finger salute as in control+alt+delete then click task manager then look at what programs are running and if that is normal and expected then look at processes and look at cpu % and watch to see if numbers spike up when the program freezes, if they do then something is hogging resources. If there aren't any then it is likely not a problem outside of Clip Studio.

You may have bad memory. What can happen is most programs use a tiny amount of system memory that is found in newer computers and everything works just fine until a program tries to use more memory then what you use normally and the errors start showing when it tries to use memory it thinks is available but isn't.

Ah, there's an idea. I'll keep that up and see if it happens sometime soon.

I did just uninstall and reinstall Clip Studio completely and then did some sketching, and it happened twice during that.

Aha! I've seen it happen a bunch of times now with the resource monitor up. Each time, there's a huge spike in LAN activity.

I'm gonna dig down into the Resource Monitor and see if I can narrow it down more.

You may be seeing the cost of some "free" software or brushes. Someone is phoning home. Clip Studio may be doing license checks, you may be a new member of a botnet or you are now bitcoin mining.

Hmm, I've never installed anyone else's brush pack.. But I did get this from Amazon's download service, you think it might be calling home for license checks? I'll do a full system scan too just in case.

Possible it is malfunctioning, typical license pings are a few bytes. Take the 'puter off the net for a while and see. Internet traffic shouldn't affect the cpu and memory but maybe...

Ahahah. Well I disabled my Ethernet and played around in Clip Studio for about a half hour, and then it finally did the freeze thing... but this time it went on for a good 30 seconds or so. I'm gonna see if the same thing happens if I have the net on, but firewall up Clip Studio.

Holy s***. I don't like to jump to conclusions, but that looks like phoning home to me. I've been seeing more and more of this crap every day. Many applications log telemetry over an extended time and do batch uploads on a scheduled basis.

My first reaction would be to use Process Monitor (from Mircosoft's web site) to capture the specific network addresses the application is trying to reach. I'd then add those addresses to my hosts file and test to make sure the application still runs. Many companies use different servers for telemtery and license checks, so by blocking only the addresses that are causing pauses, usually the application will still work normally and can still download updates. It's a better option than completely blocking the application in the Windows firewall.

Wireshark is great for packet inspection to see what is transferred, but I haven't figured out how to use it properly, yet.

Yeah, that's what it's looking like. I did get this through Amazon's "PC Download" service (their answer to Steam) so it's entirely possible that they put some sort of horrible DRM in it that calls home occasionally. But then again, this doesn't happen when I run it on my laptop.

SL350 on IB reported the same problem. He claims that downgrading your Wacom driver from the current to 6.3.13w3 solves the problem.

I wish I could investigate this, but my Intuos 1 tablet is way too old and doesn't work with the latest drivers. The newest driver I can use is 6.1.5-3, though that one causes massive lag due to constant disk access, so I'm currently using 6.1.2-5. I've known for a while that Wacom drivers are logging your every move and constantly writing to disk, and this is why people have so many lagging issues with Wacom products.

Hmm, I can give that a try but I don't think that's the problem.. Like if the pause happens in the middle of drawing the line, once the pause is over in a couple seconds, the rest of the line will be drawn following the path of motion; it's not like the pointer disappears from the start of the pause and reappears at the end. And also, this doesn't happen in SAI or any other paint program, just Clip Studio, and it can happen with the mouse just as often as with the wacom.

Never had that happen. Could be a failing HD maybe? (and it just happens that the failing sectors are where Clip Studio is)

I have the same problem, but only sometimes.
Did you try some of the 3d functionality? It seems to happen more if I make use of it.

Hmm, I play around with that feature now n' then, but it's not something I use regularly. This can happen when I've got a new screen-res document open and just sketching.

https://www.youtube.com/watch?v=jSgejNKvJ-U Fixed it for me. It's because Windows has legacy stuff left in that isn't used by modern tablets and it messes with certain programs.

Hmm, that's not exactly the problem I'm having.

Just in case any future people come here, googling these symptoms and looking for the solution, I did find it!

SOLUTION:

This turned out to be some sort of loose or short circuit in my motherboard's network card. This problem actually got worse over time, and eventually started having more obvious effects (like the network cutting out and reconnecting randomly, several times over the course of a day). I eventually disabled the LAN functions on my motherboard and instead started using an external USB-to-RJ45 network input, and this seems to have fixed this issue. I don't know why this affected Clip Studio so much more intensely than any other software I run, but boy howdy it did.
