The problem that I have is two layers are not positioning themselves correctly on the map screen, and shift position further when I pan the screen (they move closer or further away from each other, depending on the pan direction). One layer is a GeoTIFF that is correctly registered and uses CRS EPSG:32625, the other layer is a vector (country outline) that is also correctly registered with CRS EPSG:32625. The map canvas is also using the same projection.

Is there a setting somewhere that I have activated by accident?

UPDATE: it appears that that it is only the GeoTIFF that is problematic, I uploaded it to georeferencer.com and it located perfectly, while in QGIS it is constantly offset/jumps around when panning.

The data for the file reads:

I am using QGIS version 3.22.3 on a Mac.

  • Is your map canvas also using the same projection? It can be changed with a button in the bottom right of the screen. And how far are you panning?

  • The raster image may have overview layers (resampled versions with bigger pixel size). Perhaps there has happened some shift in the processing.

It may be related to this: https://github.com/qgis/QGIS/issues/46917. I've noticed the same behavior using XYZ tile layers.

  • Yes! This appears to be very similar, I do not recall having this issue with previous versions of QGIS. I will try going back to QGIS Odense and see if that works. Thank you.

  • Same here using a project that was fine prior to 3.22 upgrade. Bizarrely, the same project works fine on my M1 Mac mini, but displays this problem on my Intel Mac Air. Also appears to mistakenly associate CRSs - a blank project claimed OSGB Open Zoomstack was WGS84 Pseudo Mercator when imported...
