Brush lag/missing stroke when drawing fast

[Lindsay Wilson]

Hello,

When I'm trying to write notes using the brush or pixel brush tool in Affinity Photo, it frequently misses strokes. Probably best to have a look at the video below first. (In case the attachment doesn't appear, I also have it on YT here: 

)

I'm drawing the letter E. First in Photoshop, to let you see what should normally happen. Draw the down-and-right stroke, then the top stroke, no problem.

Next is in Affinity Photo. Notice how, frequently, it completely misses the top stroke. There's a little blip where the stroke starts, but that's about it. It seems to happen more if I try and start over the original stroke. 

Last is in the pixel persona of Affinity Designer, exactly the same behaviour.

I'm using a tablet, but I don't have any dynamics like pressure, speed etc enabled - it's just a plain off-or-on brush. It also happens when using the mouse, but it's hard to draw that fast. I also don't have any stabilzer enabled.

If I really slow the movement down, then it works, but makes it impossible to take notes quickly.

Would be very grateful for a suggestion, as otherwise it's completely useless for this application.

I had a similar problem.
Turning off Open CL acceleration helped me.

@ARTurek Thanks for the tip - unfortuately it didn't solve the problem!

If you are using a Wacom, try turning off double-click distance. It'll cause things like this. You can also try checking off Windows Ink, but try with it still on first.

@debraspicher Hi - I'm using an XP Pen Star 06. I looked into the settings but there's nothing equivalent. Besides, it works fine in Photoshop and other drawing apps, it's just Affinity that causes the problem

Hi @ARTurek,

I've not been able to replicate this using an XP Pen Deco 3.

Does this still happen for you?

Hi, yes the problem's still there. Both in Photo 2.0.3 and Designer 2.0.4. Haven't actually used the desktop software in a while, been using the iPad apps which don't have this problem, but it's still annoying.
