mouse delay while drawing?

[Terra]

i dont know what this is but when i hover my mouse over the menus there is 0 delay like on desktop or any other programm but as soon as i go over to the drawing area the mouse movement gets a delay like 100ms or something it feels like its lagging.
last time i used the programm on 1440p monitor there wasnt any issue. i have a 4k screen now.
is this normal? because is miss pixel because i can hover the mouse instantly where i want it to be.

Are you sure that pixel perfect is off? If it's on, sometimes some pixels may not be drawn (in order to ensure single pixel lines).

Are you using Linux?

no win10, it feels like the programm is running at 30 or 60fps while the menus are much more fluid. i have rtx 3080 so enough gpu power.

Try changing to the old render engine in Edit -> Preferences -> Experimental (Uncheck Use New Render Engine). It might not help but otherwise not sure what would be causing it. It's not your hardware, it's something else.

hm didnt work, sad. well thanks for the help

Also, having this issue. Whenever I draw with pencil/etc my task mgr Aseprite is using 20%+ of my CPU

I've only experienced something like this when using my drawing tablet due to Windows Ink (disabling Windows Ink fixes it). Maybe Windows Ink is doing something funky when you try to draw?

I'm experiencing extreme lag while drawing as well. i.e. quickly drawing a circle gives me a triangle.

Feels like it's running at about 15 fps. Tried clearing out all my local aseprite preferences files and editing an empty 100x100 image and I get the same behavior. :(

Edit: If I switch to the 1.2.25 branch in the Betas section, the issue goes away. Issue is present in 1.2.27.

I'm running Windows 10, i5 9600-K, RTX 2070 Super, 16 GB RAM. Also have a Wacom Cintiq, though the issue happens both on the tablet and with my mouse on a separate monitor.

Oh, ♥♥♥♥, it might be that then. Thanks

Windows 10, 32GB RAM, i9-10980HK 2.4ghz~3.1ghz, RTX 2070 Super.
I'm having this problem too.

Aseprite uses 2%~5% of my CPU, the moment I press the pen onto the screen, (pixel perfect off, 1px brush size) it starts going to 10%+
Aseprite seems to only use about 64MB of my ram as well, I obviously wouldn't mind allocating 35 times that amount if it would stop the lag...
(I'm using the 1.3 Beta because the ability to drag preview to another screen REALLY helps me out)

EDIT:
Very important for me to mention, it seems to lag mostly when using the pen rather than when using the mouse, I use a Huion Kamvas 22+

Edit 2:

1.2.25 branch indeed doesn't have the problem, like thatpixelguy suggested.
