Created attachment 108871 [details] Strokes showing the bug's effect. Brush is registered as a straight line for approx. 300ms from the start of the stroke. This is true of both mouse and stylus, and of every single stroke. I have flagged this as a major bug since this renders me effectively completely unable to draw anything. The only way to fix it seems to be to wait out the lag period, then trace. I should mention this doesn't happen in Photoshop CS6 on the same machine, and that I have allocated 100% RAM to Krita and set it to run realtime. These are the only settings I have modified from the defaults. Krita is also running from an SSD with a comfortable 32G of empty memory.
Does going to view->instant preview help? Are you also sure you didn't turn on stablizer on in the freehand brush tool options? Which version of Krita is this anyway? I am not sure if 100% ram is really wise, but I believe that is seperate from this issue.
What tablet device are you using? Also, please provide the info from Krita "Help"->"Show system information for bug reports". (Protip: Setting a process's priority to realtime does not do what you think it does. On Windows, mouse input doesn't even run as high as realtime priority, so if a realtime process ends up using 100% CPU you won't even be able to use the mouse.)

Instant preview does not change anything, and I have no smoothing mode enabled on the brush

I have an Intuos Pen and Touch small ( CTH-480 ) I have added system information to a separate comment. I know it doesn't change that much but it has fixed some lag issues for me in the past so that was one of the first fixes that came to mind. But thanks for the tip !
What if you disable "Canvas Graphics Acceleration" in configure krita->display? Or change renderer to ANGLE?
(In reply to Alvin Wong from comment #6) > What if you disable "Canvas Graphics Acceleration" in configure > krita->display? Or change renderer to ANGLE? Both fixes tried, not working :/
Can you make a tablet log by following this? https://docs.krita.org/KritaFAQ#What_if_your_tablet_is_not_recognized_by_Krita.3F Draw a few circles while making the log. Try to make at least one fast stroke and one slow stroke. Please also take a screenshot of the result so we can correlate the tablet log with the strokes drawn on the canvas.
Marking as waiting for info -- we need to see the tablet log.
Created attachment 109384 [details] Tablet Log This is a tablet log of me tracing three circles all showing the problem
(In reply to Azher Krimson from comment #10) > Created attachment 109384 [details] > Tablet Log > > This is a tablet log of me tracing three circles all showing the problem Well, it's obvious from the log that the driver sends several move events with the same coordinates but varying pressure, then sends more move events with a big jump. I'm feeling a bit dumb for not asking these earlier... - Are you using the latest Wacom driver? - Which version is it? - Does it happen if you disable Windows Ink in the Wacom settings? - Does it happen if you enable Windows Ink in the Wacom settings and change the tablet API in Krita to Windows pointer input? (You need to restart Krita for the changes to apply.) - Does it really also happen with the mouse like you mentioned in the OP?
Driver is updated to version 6.3.25-5 which should be the latest The problem happens whatever Krita's pointer API is set to and whether or not windows ink is on. Despite the log showing the driver malfunctioning, I must mention that photoshop on the exact same machine does not experience this issue at all and draws smooth lines from the get go.

I literally just tried the same model CTH-480 with the same driver version 6.3.25-5 and there aren't any issues. I suggest you reset the Wacom driver configuration completely with the Wacom Tablet Preference File Utility, make sure no remnants of possibly broken configurations are in place, uninstall the driver completely and install it again (_not_ simply reinstalling). If this doesn't change anything, I'm afraid there is something seriously wrong with your system that we can't fix here.
Bug was probably due to an improper driver upgrade, thank you for your help. As obvious as it may sound I had not tried uninstalling and reinstalling the driver, because I thought the fault couldn't possibly come from it as every other program (including FireAlpaca, Photoshop, Paint and Sketchpad) were working perfectly fine. Thank you for your time !
