Created attachment 127349 [details] Wrong aspect ratio I'm using the file from bug https://bugs.kde.org/show_bug.cgi?id=419715 With Krita 4.2.0-preview, the thumbnails for the layers with the color blocks have the right aspect ration. From 4.2.0 on, the aspect ration is distorted.
Created attachment 127350 [details] correct aspect ratio

This really needs to be fixed...
David Revoy gave us a bit of a tip when the regression happened: > boud: dmitryK|log : From my screenshot of Krita GUI while making Pepper&Carrot; the layer ratio thumbnails regression happened between 4.2.5 and 4.2.6 (around April/May/June/jully 2019). Sorry to can't be more precise. eg. https://www.davidrevoy.com/data/images/blog/2019 > /ep29/2019-04-18_screenshot_142122_net.jpg (4.2.5) the ratio of page reflect on thumbnail in layer stack > while 16 jully: https://www.davidrevoy.com/data/images/blog/2019/2019-07-16_screenshot_151926_net.jpg , all square layer thumbnails
I think the offending commit is this one: 097d7e617aa260d467f86e65f8c6edfdd6124ea9
