Hello everyone I'm new to digital design/art, never used any programs other than Affinity. I've been using them in my spare time trying to learn everything I can about them. I've scratched the surface of the tutorials, seems like theres an abundance of them. I've also searched thru the forums to find help with my issue, which brings me here.
In AP 1.6.7, in the photo persona, sketching on a blank canvas, I would like to flip the canvas horizontally/vertically, often. I can do so from Document>Flip Horizontally/Vertically at any time and it works flawlessly. My problem happens when I attempt to use the shortcut for this action. When I hit the shortcut key(s) the canvas basically does nothing, and eventually starts to slowly flip blocks of pixels at a time, which can be sped up by moving my cursor over every part of the document that hasn't flipped yet. Sometimes they don't flip at all and I have to go to the Document menu and click flip v/h to get it to right itself again. This happens whether theres one line on the page or a thousand. Occasionally the shortcuts will work after I do it 3-6 times in succession, but will go back to not working correctly after continuing my work. I've gone thru all the tools to figure out this happens when using the paint brush, dodge brush, erase brush, burn brush, sponge brush, blur brush, sharpen brush, median brush, smudge brush, gradient, pixel tool and color replacement tool. Every other tool will allow me to shortcut the canvas flip horizontal and vertical exactly the way I assume it's intended to be, instantly. I haven't messed around with the settings much at all, I did try changing the shortcut keys and reverted back to default when there was no change. There could very well be something I'm missing or not doing right, and I hope someone out there can shed some light on this issue. Thank you in advance for any response.
