The problem seems to happen only on IplugResponsiveUI demo, I’m still investigating, tried setting PLUG_HOST_RESIZE 0 with no effect, will report any other findings, any tips appreciated!
Thanks but this also happens on any DAW using windows 150% zoom on IplugResponsiveUI demo, I haven’t had much time but I think not all Iplug demos suffer this issue so there may be a work around.
