Good day, sires. I am an early adopter of Krita 3.0 and I would like to report that I am encountering brush lags when painting at zoom level 50 and below. Given that I am into producing high resolution pages for my comics project, the lag is somewhat crucial - especially since I have not encountered the lag issue in version 2.9.10. Reproducible: Always Steps to Reproduce: 1. Create a new high-resolution document (default "US Letter" settings with 300 dpi will suffice) 2. Pick any brush (more dramatic with the "Bristles_Wet" item) 3. Set the zoom level to 50% or below 4. Quickly draw something on the canvas. Actual Results: Brush is rendered with delay Expected Results: Brush is immediately rendered
My PC's specs, by the way: AMD Eight-Core Processor, AMD Radeon R7 260X, 16 GB RAM, Windows 10, Krita installed in an SSD In short, the PC is more than capable of graphics rendering. Hopefully this helps.
Are you using the brush stabilizer by any chance? AMD GPU's seem to block the gui for a longer period than Intel or NVidia, and we encountered a problem with the stabilizer option coupled with AMD gpu's -- there is a fix for that in 3.0.1, with a dev build available now: http://files.kde.org/krita/3/windows/devbuilds/krita-3.0-da5496d-x64.zip
Good day by the way, sir. I don't use the stabilizer. I just use basic smoothing. I will try the dev build ASAP to check if the issue is fixed. But I would also like to note that whenever the brush lag happens, the Overview panel sometimes acts funny (it zooms out for a second then zooms in to "normal") . I would not know if this is related to the problem though.
Ah -- that could be related. Does it make a difference if you hide that?
I haven't tried yet. Let me check later.
Good day. I tried the dev build, and the brush lag is still present. I also observed the Overview panel is the same for the dev build, acting funny with zooming in and out. I closed the Overview panel, and the brush lag is still there.
Hi. Try turn off: "Settings >> Configure Krita... >> Display >> Use texture buffer". After this please give feedback :).
Hello :) Turned off the texture buffer, and the delay is still there. And oh, brush lag also happens when I make a quick line streak using the mouse.
Hi again It sad that it doesn't help... Lately somebody else (nick from krita's IRC channel: 'Stratosfear') has reported exactly the same issue on IRC... He also has AMD CPU. His hardware specs: System Manufacturer: Gigabyte Technology Co., Ltd. System Model: GA-MA785GT-UD3H BIOS: Award Modular BIOS v6.00PG Processor: AMD Phenom(tm) II X4 945 Processor (4 CPUs), ~3.0GHz Memory: 8192MB RAM Card name: NVIDIA GeForce GT 220 For he my solution has resolved this bug :). I also have Nvidia card (GeForce G 103M) and Intel CPU. I have some similar slow down and for me turned off "Use texture buffer" also helps a lot... It looks like this turn off gives boost for Nvidia only.
Just dropping in to say that this bug might be either related to, or a duplicate of, a bug I filed a little while ago: https://bugs.kde.org/show_bug.cgi?id=363487 Looking at the how the brush behaves, it does look like it performs much worse at below 50%, though it's the issue present at higher zoom levels for me. I haven't seen any odd behavior coming from the overview docker, but I wouldn't rule it out either since I don't use it too much. Most interesting to me, and what tells me that this might be the same bug, is that we have very similar graphics cards. My card is an ASUS Radeon R9 280X, which is apparently an AMD-based card from the same series. On a slightly-unrelated note, the bug I linked appears to be mislabeled as resolved, since I initially reported it as possibly fixed, when its behavior changed after I updated my graphics drivers. I should probably set that to something else, but I can't figure out for the life of me what I should relabel it to. Regardless, thanks for your time everyone, and here's to getting this bug solved!
hello! i just recently started using krita but when i try to draw with zoom 50% or below 50% it lags :( i have Windows 10,installed the 64bit ver and im using huion tablet
Good day, sires. I tried Krita 3.0.1 to test the presence of brush lag, and I would like to report that the problem is partly solved for tools with small dimensions (such as the gpen tool at px 10). On larger dimensions (such as hatches set at 128 px), the lag persists.

Good morning sires. I would like to report that I just downloaded Version 3.1.1 and observed a much better performance in rendering fast and large strokes, with lags that are much more manageable. I would also like to note that it seems there are tools that lag pretty much (i.e. Bristles_hairy and Hatch_cross_small) and tools that don't lag (i.e. Basic_mix_soft), which may be expected given the inherent complexity of programming the other tools.
Yes... We worked really hard on improving performance already.
