The Preview PDF handling drives me mental too. Luckily it's not outright unusable for me, but it's still a pain. Buy Apple, they said... Apple always looks after the details :( Happens on both my Macbook Pros, too - a early 2015 13" (i7-5557U) with Sierra, and a mid 2014 15" (i7-4980HQ with discrete GPU) with High Sierra. The symptoms for me, with the proviso that I'm not in OS X right now to double check: 1. set Preview to open PDFs at 100% zoom, 1 page at a time. Open a PDF. Preview opens the window at the right size, then pops some scrollbars in. Now the client area is smaller, and that means the window is the wrong size! - which means the mouse wheel scrolls the view, rather than scrolling from page to page. Gets me every damn time. (This could be related, I imagine, to that setting that forces scrollbars always to be displayed. I suppose it's too much to expect Apple's QA to have a test matrix that encompasses this case) 2. scroll from page to page. Each new page appears blurry - or, if lucky, merely wonky - for a fraction of a second, then replaced with the clearer rendering one might expect. Actually quite distracting when scrolling page by page! - and when scrolling at keyboard repeat rate, the clearer version never has time to appear, making it impossible to scroll through a document visually at full speed 3. when resizing the Preview window, some sizes look mucky - looks like the sort of thing you get if you render to an offscreen buffer that's 1 or 2 pixel the wrong size, or add the 0.5 to only one edge of your quad, and so on. Really annoying |
THIS drives me nuts.
