* Could you try switching the canvas acceleration to Angle?
* Disable any 3rd party python plugins?

I've tried switching all the canvas acceleration modes, but nothing has changed, and I've hardly used any plugins.

I was using the 5.3 beta version, but it became extremely laggy after a recent selection tool update.

I'm trying to find a version of 5.3 before the selection tool update, as previous versions worked perfectly. But I can't find it. Could you please provide a September 5.3 beta version?
Comment 3 Bug Janitor Service 2025-11-29 03:46:25 UTC 
🐛🧹 Thanks for your comment!

Automatically switching the status to REPORTED so the team can perform further triage.

In the future you may also do this yourself when providing needed information.
Comment 4 Halla Rempt 2025-12-12 11:54:28 UTC 
We don't really keep old nightly builds around, so I'm afraid we don't have one. If it's between now and September, we could try to git disect it. My windows machine is currently out of action :-(.
Comment 5 Ming Chuan 2025-12-12 12:08:54 UTC 
I assume by "recent selection tool update" you are referring to selection action bar? Does it still lag if you disable it in Configure Krita -> General -> Tools -> Selection Action Bar?

Hi, jackstone!

Could you please record a video showing the issue?

i try to dissable Selection Action Bar setting ,It didn't work, is still very laggy.

Comment 9 Emmet O'Neill 2026-03-17 04:48:43 UTC 
I've tested this today (on a vanilla Windows 11 install, not window 10) and I can't seem to reproduce it on my system.

I've tested the latest Krita Next alpha nightly vs 5.2.16 stable and I have seen no perceptible difference in drawing or GUI performance, using my laptop pen or mouse controls. I'm certainly not seeing anything like the video that jackstone has shared. :\
Comment 10 vanyossi 2026-03-17 21:23:57 UTC 
Sorry but I could not reproduce it either on krita 5.3.0-beta3 on windows 10

Testing using OpenGL (not Angle), with the latest nvidia drivers ("4.6.0 NVIDIA 595.79")
Comment 11 Dannel Gutiérrez 2026-03-21 18:42:05 UTC 
I've been experiencing this same issue since Beta 1, although in Beta 3, Krita feels a little less heavy.

I tried the portable version, cleared my settings and my Krita folder so there are no plugins or settings that aren’t included by default, tested it with my integrated graphics (Intel Iris Xe Graphics) and my dedicated Nvidia graphics card (RTX 3050), and switched from Angle to OpenGL, but the lag persists in the menus.

Hi, Dannel!

Do you have the lag with both, Intel **and** NVidia GPUs? Or only with one of them?

Hi, all!

Could you tell, is this issue intermittent or persistent? I mean, does it appear on every run of Krita or only sometimes? And, does it go away if you stop touching mouse/tablet for about 20 seconds and then start again?

Hi, I'm experiencing lag with both GPUs.

The issue persists; every time I run Krita, the menus are still laggy.
I ran some tests, stopping using the tablet and mouse at times to see if the lag would go away, but no, the issue is still there.
Comment 16 Dannel Gutiérrez 2026-03-25 06:09:00 UTC 
By the way, just to clarify, I'm using Windows 11 25H2, since I see that my first comment shows Windows 10 in the OS version information, but that's not the case.
