Edit viewer displays only work in 4:3 aspect ratio in SD

I recently revisited an old project shot in 16x9 SD on 15.2.4 on Win 10 and cannot get an SD time line to display the correct aspect ratio.

The source material is all set as 16x9 and shows a such in the media pane, and when the time line is viewed with a standard 1920x1080 setting all looks fine. However changing the timeline setting to PAL SD 720x576 16:9, The display in both source and edit viewers is 4:3.

If I change the timeline setting to 4:3 the viewers display is still 4:3 and the material is shown letterboxed within it. (and small as its not using the full viewer space, so its letterboxed in a pillarbox!) Turning on the aspect safe area display confirms that the viewers never use the full width.

However if I go to the deliver tab the viewer is the correct shape.

So basically whatever I do, in PAL SD the viewers always work within a 4:3 raster. Is there a way round this or is this a bug?

Currently I'm setting the timeline to HD, but having to remember to revert for delivery.

I think it was always like this. Basically Resolve shows viewer at square pixels (or 4x3 aspect), so for SD formats with non-square pixels you edit with squeezed preview in the viewer.
Color page is fine though

As is the delivery page. Seems a bit of a silly omission though. Thanks for confirming it was always like this, long time since I did SD......

Yes, maybe 1 day it will get fixed.
