I'm using the Map Swipe Tool in QGIS 3.6.2 on a Mac and a PC. I'm using the tool on two imported raster layers to compare changes in temperature. On the PC, it works just fine. On the Mac, I'm getting a lopsided image (see attached image). I don't know if this is Mac related or not, but does anyone have any ideas on how to fix this or why this might be occurring?
