Overlay Problems with usages of GPU support

Hello,
has somebody an idea how to solve this overlay issue when GPU support is enabled with an 4K screen? When the GPU support is enabled I see only an active windows on the upper leften side of lightroom. The GPU of a GTX 2070 should not be the problem.
Yes, I an disable the GPU support but then the performance decrease. I would like to work with full performance.
I am very thankfully for any hints to solve the issue.
Regards,
Mike
