I am not sure if this has been asked before or not.
I am trying out Solus 4.2 from today.
One thing I found quite strange in Evolution (I prefer Evolution to any other mail client) is that the icons are 'appear' disabled even when they are active. i.e. they have the same color combination as a disabled option.
Is there any option to resolve this?

If you notice the toolbar - the delete option is very much available, but if we look at the button - it looks like disable (when i clik on the button, it works).
I am on Solus 4.2 (All updates applied)
Evolution Version: 3.38.4
