dshanaur Sorry for the confusion. What I recommended was upgrading both your Spine Editor and Spine Runtime at the same time when version 4.3 is released. It is not advisable to export only the skeleton data in the 4.2 format while using the 4.3 editor.
In any case at least switching back and forward between versions helps somehow rn.
We do not guarantee forward compatibility. Doing so would require a significant amount of effort and ultimately make it difficult to add new improvements. Instead, we minimize runtime changes, provide scripts that make it easy to upgrade large amounts of skeleton data, and offer immediate support to users who encounter problems during the upgrade process to make the upgrade easier.
Are you perhaps enabling color management? If so, you may want to set the interface scale back to 100%. In versions prior to 4.3, using an incomplete scale, such as 110%, with color management may cause layout issues.
