Hello Team,
I was switching the project from 6.2.6f2 to 6.3 latest version. I noticed for some reason the scenes were stretched completely. UI was intact but all the other 2D renderers were stretched. So then I started going 1 version behind in 6.3 to see from where it originated. I have tested all version from 6.3.5 to 6.3.18. The last safe version with no stretching issue was 6.3.15, after that all versions have this issue.
Is this is Editor bug or is there a setting that was introduced that I am not aware of. I made windows build to test if this was only on editor , the issue stayed on the build as well.
Do not just jump version, especially not downwards as this is unsupported and can lead to loss of data. If any asset’s serialization format changed during the upgrade, and was saved in the newest version, the older versions will either lose that new information or interpret it differently (silent failures), and other issues.
Best to delete the Library and Obj folders now to start from a clean slate and observe any issues in the console that weren’t there before, if any.
Check the transform scale of all parent objects. You may have accidentally set a parent’s scale to 2,1,1 (for example) and that would stretch all children horizontally by a factor of 2. They would be stretched in the scene view too. If stretching only occurs in the game view, please post a screenshot so we can see what’s going on. “Stretching” may mean something else than others think you mean by that.
