Transparency not working

[GreenSokrates]

Hello everyone,

Since a couple of days the transparancy stopped working For example in the latte-dock(see image), in terminal (background) or in rightclick menues

Im running Mint 18.3 KDE Edition, with Kernel 4.13.0-45-generic.
CPU: Intel i7-5500u
GPU: Intel 5500u HD-Graphic

Additional info:
~ $ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Broadwell-U Integrated Graphics (rev 09)

Edit:
If i boot from kernel recovery mode all works. Any solutions / ideas?

I have exact the same issue since the last update. I don't know if it is software related or kernel.
