verysame's answer is great, but I find the set up of channel mixers can be simplified as: - If you want just the Red channel, simply change all the rest channel's contribution to zero. For instance, after you duplicating the original image 3 times, and rename them properly as "Original_Red", "Original_Green", "Original_Blue"; Add 3 channel mixers to each later. Now inside the Channel Mixer for Original_Red, select green output and change its green contribution to 0, select blue output and change its blue contribution to 0. Similarly, inside the Channel Mixer for Original_Green, select red output and change its red contribution to 0, select blue output and change its blue contribution to 0. Finally, inside the Channel Mixer for Original_Blue, select red output and change its red contribution to 0, select green output and change its green contribution to 0.

I really wish they take it more seriously. How hard it is to replace brush preview with just names? This issue is clearly more political than technical. I have to purchase F**king Adobe Photo plan just for using my brushes! P.S. I just discovered you can hover your mouse over brushes and it will show you brush names rather quickly. So it's really fine.

@stokerg Thanks for your reply! I changed Tablet mode to high accuracy and that solved the issue. @Next Leo Thanks for your follow up! It's unfortunate but it's glad to know I am not alone on this issue. However, I couldn't reproduce your issue either. But I suggest you try: 1) Recording using OBS Studio or NVIDIA GeForce Experience; 2) Change tablet mode to high accuracy and see whether that solved the problem.

There is something else that seemed similar though I am not sure whether relevant or is just different bug: when I switch my pen to the eraser (Wacom Intuos Pro pen has an eraser at end) outside canvas area it sometimes (usually) doesn't detect this, and remain in Brush mode instead of switching automatically to Eraser mode - this happens especially when you are doing this rapidly. Similarly when you switching back to pen from eraser it sometimes doesn't detect either. As you can see from video above, I don't think my computer's spec should be an issue - most likely it's a software issue. Again, same thing doesn't happen in other drawing softwares.

As you can see it happens almost every other few strokes and is very very annoying - and frustrating 😢

I am not really sure whether this is a compatibility issue between my Wacom and Affinity, but when I use Sketchbook and other paint software no such issue exist, so I suppose it's Affinity Photo's configuration issue: When I draw in Brush mode, and especially when making detailed strokes on a smaller canvas area, sometimes one or both of the two things happen: 1) The starting stroke automatically connects to a previous ending stroke; 2) After ending a stroke the next stroke simply doesn't show up - no matter how hard you press or draw. To fix the first issue obviously the only way is to "undo", to fix the second issue I just need to raise my hand and start a new stroke. It's a bit hard to describe and I cannot even reliably reproduce this because this happens almost randomly and I haven't seen any pattern yet - except that it seemed that if your starting and ending strokes are very close together it's very likely to happen. This used to confuse me when I was using Color Replacement Brush Tool, but in this case I am sure I am not using Color Replacement Brush Tool. Please see corresponding video for details - notice while I was writing "D" it was two strokes, one stroke for the line, the other stroke for the curve, but for some reason the second stroke tends to get lost. While I was writing "=" sign however, not just the second stroke get lost, the first stroke connects to the second stroke's starting point. I am affirmative this happens only with Affinity Photo (and Publisher, for that matter) - it doesn't happen with Sketchbook or gInk.

Doesn't seem to work for Photo mode inside Publisher.😶

That would be great if there is a "mute" button for effects.

This button totally doesn't work when brush size gets small. There should be a "always hide brush crosshair".

Totally agree. I always feel Affinity Photo brush is even slower than gInk.exe partly because of that distraction.

I am experiencing same issue with Affinity Photo/Publish on a 1080p document. In the past I always thought my machine/brush was not usable because of the large latency. Now I realize if I zoom out it's noticeably faster. It's hard to see from the video alone although it's already 60FPS - it's much more perceivable when you are actually drawing it with a tablet. I think it's expected because it's issue with hardware/software latency.

For the moment the problem can be mediated by creating a new category.

I have been following this problem for years and here and then it comes up. I can't believe no one is doing anything about it! I really annoyed by now.

Damn, is this still not solved? I mean, it's a great tool.

I totally agree. Someone should take care of this.
