I've just installed Zend Studio 13.5 on my new Dell XPS 15 laptop, (3840x2160 display resolution) and it's practically unusable, the toolbar icons are so small.
Even with Windows scaling set to 300% doesn't seem to modify the icons.
I've googled a bit and it seems to have been a problem for some time.... (Several years!!!) but the workarounds seem mainly aimed at Eclipse and the Zend implementation doesn't seem to have the files they refer to.
Can anyone help me please?
