Mouse lag/stuttering on the UI elements

[ΛMNESIΛ]

Nasty bug, present in the 2.0 apps at launch, is back again after updating to 2.3.0.

RTX 4070, Gsync active for fullscreen apps only, tried disabling openCL, nothing helps.

No problem with the apps just being open (designer and photo), everything is fine and smooth. But immediately after opening/creating a new document, mouse becomes laggy as hell, as soon as the cursor touches the UI elements. It's like going from 165hz to 20hz refresh rate in a milisecond.

Other apps are working just fine, please fix this bug once and for all. I have a lot of work to do right now, and this problem is making the apps basically unusable.

 

EDIT: completely disabling gsync "solves" the problem.

Still, this is unacceptable, IMO.

Hi @ΛMNESIΛ,

While the original issue was solved at one point, it was reopened due to it coming back.

I've added a link to that report back to this thread so the Serif Info Bot can update when this has been resolved.

 

[ΛMNESIΛ]

@stokerg Thank you.

@ΛMNESIΛ

I am looking at this in 2.4 and I'm seeking a few volunteers to re-test this in 2.4.0 Release - can you confirm if this is still an issue for you, please?

I can confirm it is still an issue.

[Chris B]

Thank you. I will update the bug report and inform the developers.

This is also an issue for me on 2.4.2, I am using a 13900k CPU and a RTX 3090 Ti. The monitor I use has a refresh rate of 144hz.

[ΛMNESIΛ]

I just updated to 2.5 and the bug is still present. This is getting really annoying. Any info on the progress, workarounds, solutions?

I understand it might be difficult to fix this problem, but come on. It's been 6 months since my first post.

[ΛMNESIΛ]

Nvidia finally released a good driver, DDU, fresh install, mouse cursor still lagging. Looks like nobody cares about this super annoying bug.

[glitch_glo]

I'm experiencing the exact same, the mouse is lagging over the tools. But this only happens when the Affinity window is active. If I hover over the window when another window is active, then it doesn't happen.

I just tried the 2.6 beta versions and the problem still hasn't been fixed.

I can confirm this exact behaviour.

Also getting this issue. Very annoying.  2.5.6 

 

Using a Wacom Intuos Pro Medium.  After I finish a few strokes the cursor will lag for a few seconds before becoming smooth again. It also happens when moving the cursor to the UI elements outside of the canvas in Photo sometimes. 

 

When Force Pressure sensitivity is ON - the cursor will lag in the canvas after I finish making a brush stroke. Cursor will become smooth after a few seconds of lag.
When Force Pressure sensitivity is OFF - it wont lag after the brush strokes but it will lag when moving the cursor up to the UI elements outside of the canvas.

 

Can provide additional details if it helps the dev team solve this.

I'm also having this issue. Makes it very hard to use the software. Was looking to move from illustrator but it is pretty worrying that an issue this bad hasn't been fixed for over a year.

 

@Chris B @stokerg  Any updates on this?

 

Edit - Can confirm that disabling g-sync fixes the issue. It should still be fixed though.

Found out that g-sync fixes it

Hey @JDBB The problem we are having is reproducing this with a developer in order for them to fix it.

We've even acquired hardware specifically for this issue and the issue hasn't presented itself at the time of testing. 

Can you confirm whether you have an RTX card and if so, which model? We've tried using a 3 series card and I've found someone who's got a 4 series card and I'm waiting on them to retest. 

Did you disable G-Sync globally or on a per-app basis? I believe there's a tab under 3D settings to disable it for a specific app.

@Chris B

My card is: NVIDIA GeForce RTX 4070

I can test something if that helps.

I disabled g-sync globally. I have looked to disable g-sync for affinity designer alone but affinity doesn't show up in the list of applications in the 3D settings menu for some reason.

[Chris B]

I wonder if you have installed the MSIX version (which, AFAIK should still show up in there).

If you can go to your Affinity account and download the .exe version of Designer, you should be able to see it in that list or manually browse to it using the Add button.

@Chris B

It looks like I did use the MSIX version (I can see the msix file in my downloads folder).

I can manually navigate to the exe and add it to the 3D settings list. However this doesn't fix the lag issue.

I haven't tried downloading the exe instead yet.

 

 

 

I should also mention that my g-sync is set to only be enabled in full screen mode so not sure why it is affecting affinity in the first place.

[Chris B]

Hey JDBB,

The MSIX won't work as the path will change on each update of the app and would just prove to be highly unreliable. Even the .exe might not work and I cannot reliably advise as we haven't reproduced it.

I understand you are stuck between a rock and a hard place. I've asked our IT team today if there's any more hardware we can try testing on. I'm still waiting on the person I asked who has a 4 series card to see if they also have the G-Sync module but they are on annual leave.

That's because the GPU thinks that Affinity is a full screen program (or maybe even a game, I don't know).

If I turn on Nvidia overlay and start Affinity, that Nvidia logo will come up every time. It shouldn't.

I also tried the .exe version, same problem. Turning G-sync off for the Affinity only causes other problems, like screen flickering and black squares.

 

I'm really hoping they will find a solution soon. I've been turning off G-sync manually for the past year and it's just tiresome.

😔 I agree we absolutely need to fix this. I'll update you all once I get some more hardware.

[Playmo]

Just wanted to say this is an issue with my software as well, as of february2025. Tried changing different settings withing Affinity software, adjusting ram size, turning on and off GPU acceleration etc but no luck.

Added a short video clip to show how it behaves.

GPU 4070
AMD 9800X3D

64 GB DDR5 RAM.

Do you use G-Sync? If so, try with deactivated G-Sync.

[mynamehere]

Been having this issue for years now...

GSYNC On: Laggy mouse

GSYNC Off: Everything works

It worries me that a bug like that can exist for so long. A lot of us have high end monitors in this business.

Im on Ryzen 3700, RTX 3080, Screen AW3418DW

[Chris B]

Hey mynamehere,

I have a AW3423DWF and an RTX 3080 and I cannot reproduce it. 

We believed the issue was down to the monitor having a dedicated G-Sync module which I believe mine does not as it uses FreeSync. 

Can you tell me if you're using HDMI or DisplayPort?
