The canvas interpolation is poor when not at 100%. I created an image, and it was fit to the screen at 106.2% zoom. It looks like the image is rendered in tiles, and they are not correctly aligned. See attached screenshot.

Potential compatibility issues with the latest XP-Pen driver and Affinity apps (just posting in the Photo forum as this is where I noticed it first). After installing the latest update I've noticed that the strokes I make using the brush tool (or any tool for that matter) result in jagged lines - attached a screenshot below. The further I zoom out of my canvas the worse it gets, almost as if the lines start snapping to an invisible 90 and 45 degree grid, or as if the resolution decreases the more I zoom out. I'm using a late-2015 iMac running macOS Big Sur Version 11.1, and the tablet I'm using is the XP-Pen Artist 22R Pro. I would have assumed this was an XP-Pen issue, however, the tablet seems to be working perfectly in other apps. I've brought this same issue up in the past, it was then resolved in an Affinity update, but now it seems to be back with a vengeance - really hoping there's a fix in 1.9! Here are the previous posts I'm referring to: 1. https://forum.affinity.serif.com/index.php?/topic/85155-by-design-aliasing-issue/ 2. https://forum.affinity.serif.com/index.php?/topic/93763-whole-pixels/

Stylus input on desktop (Mac) isn't nearly as smooth as on iPad, no matter what tablet drawing brand you use (I've tried a few). I've brought this up before, and it's kind of a biggie, considering there's a ton of illustrators, designers, photo retouchers/editors, using drawing/graphics tablets for their work. Some some reason this only happens with Affinity apps, and I haven't had this issue with any other graphics software. It's not a deal breaker per se, but it's very notable, and if you use a drawing tablet most of the day for your work, it can get quite frustrating (and could potentially put future users off of using the apps altogether). Furthermore, if you want to compete with the industry leaders (*cough Adobe), then you need to ensure that your stylus/pen input engine is pristine or at least on par with something like the industry standard, Photoshop. For some reason the pressure sensitivity has a tendency to spike or be slightly inaccurate and the lines aren't as smooth as they should be (often with small, but notable kinks and jitter). This is also very notable when using the Freehand Selection tool with a tablet. It's even more prevalent the more you zoom out of your canvas, causing weird jagged 90 and 45 degree angles in your lines/selections - almost as if the pen cursor is snapping to an invisible grid 90/45 degree grid. I usually do not work very zoomed in, so this can get very problematic throughout the work process, causing unwanted kinks and jagged lines which I've never experienced with any other drawing apps. To combat this, I've been using a third party plugin called Hej Stylus (hejstylus.com), and the pen input from my drawing tablet on desktop has been so much better within the Affinity apps while using it. It overrides the apps' default pen input in Affinity and replaces it with Hej Stylus's settings, which are much nicer and more accurate. When using the Hej Stylus app, I keep all the settings at an absolute minimum so that there isn't any additional smoothing, and all the app essentially does is override the default input. I don't necessarily want to use a third party app when working, but I'm doing it out of necessity. I think it's important to note that a desktop drawing tablet is a lot different from an iPad/Apple Pencil combo. The desktop styli/pens act differently and require different settings to perform the way that they should. Perhaps there's a way to get Eilert (the dev over at Hej Stylus) on board to help sort out the stylus input issues in Affinity apps. Sorry to keep going on about this, but as someone who uses a drawing tablet on desktop for ALL my work (as very many illustrators do), I really want to keep using Affinity without any tedious workarounds which takes extra time, and ultimately costs me and my clients money. Really hoping for a fix in the next update!! I've attached a screenshot here of the issue, and also attached the file: HejStylus Test.afphoto
