@nyalldawson , is that still a limitation in Qt 6? I feel we've discussed this in the past for layouts. |

The message bar here is less than ideal as the dialog is narrow by default and the key part of the message (raster will be truncated) is barely visible. Maybe rephrasing the sentence so the consequence appear before the width/height could work better. |
Reworded to "Output raster will be truncated, as image width or height is larger than 32768 pixels." |
