Meorge Posted June 24, 2020 Share Posted June 24, 2020 Recently as I've been doing drawing/painting in Affinity Photo, I've been experiencing a strange bug. Seemingly at random, my brush strokes will act as though they're being masked by what's already on the current layer. This often results in me not being able to paint over areas with partial transparency (only where there is no data for the layer), but sometimes it will also prevent painting in certain areas where there is no data. Restarting Affinity Photo always seems to fix a particular instance of the bug, and using my trackpad to zoom on the canvas sometimes works. I've attached a short video I recorded that will hopefully make the bug easier to understand. I'm really liking Affinity Photo so far for my digital drawing and painting - it's way smoother than Krita! - but this bug is making it difficult to get work done quickly. Please let me know if there's any more information I can provide to help here! Thank you!

However, I think I did discover today what the "bug" was! To switch between brush and eraser mode, I'd often press the B key on my keyboard. I thought that this simply toggled between the two tools, but it looks like it was actually switching me to the "Colour Replacement Brush Tool", which gave the strange behavior. Since I took note of that earlier today and began switching explicitly to the normal brush, I haven't had the issue anymore! Quote Link to comment Share on other sites More sharing options...
