Created attachment 123550 [details] Example file with Transform Mask that shows the issue SUMMARY On HighDPI display the decorations that you can turn on using the Show Decorations button (the one next to the spider/recursion button) is displayed differently depending on the zoom. (In my case with 150%, it the decoration showed the original position and size of the selection before making the transformation, but all other zoom levels change the position of the decorations. STEPS TO REPRODUCE 1. Open the attached file. 2. Select the Transform Tool. 3. Select the Transform Mask. 4. Click on the canvas. 5. Zoom in and out. OBSERVED RESULT The grey rectangle is changing its size and position according to canvas because of the zoom level. EXPECTED RESULT The grey rectangle should get bigger and smaller depending on the zoom level, but it should keep the same size and position regarding the canvas. ADDITIONAL NOTES I used Transform Mask for the example, but it happens with the Transform Tool, too.

I can confirm this for the latest 4.3.0 prealpha (git 2c21a4c) appimage. It happens if Hi-DPI is enabled or not (but my display is not Hi-DPI so that may not be relevant). As well as step 3. Select the Transform Mask, you can do Select the Paint Layer instead and you get the same effect but with the decoration rectangle showing the final transformed result bounding box instead of the source bounding box. The decoration is not resized on the screen as zoom level is varied. It stays the same size on screen and so appears to change size relative to the canvas. The decoration offset from 0,0 top left canvas is not resized on the screen and so seems to move across the displayed canvas as zoom is varied. This becomes apparent if the source or final transform bounding box is made to fit up into the top left of the canvas and the appropriate layer is choosen to show this as decoration. Then it stays in position but has the zoom/size problem as noted before.
Git commit 8c53a59da010ec2bcd99593d8784023fc3ebd3d9 by Dmitry Kazakov. Committed on 11/11/2019 at 11:17. Pushed by dkazakov into branch 'master'. Remove Show Decorations option from Transform Tool This option didn't work for several years and noone noticed that. I'm also not sure it is possible to make it work in a sane way for new transformation modes, like "Cage" and "Liquify". It seems like the option didn't work right from implementation of these modes.
