This beta build has some more fixes, particularly for systems with NVIDIA GSYNC enabled.

Change Log

Changes since 5.1.1 Beta (build 9098):

• Fixed Edit->Cut and Edit->Crop to Selection not zeroing out transparent pixels, which could be a privacy issue.
• Fixed swapchain valid rect propagation, which may fix some cases of flickering or trails that have been reported.
• Fixed some crashes and blanking screen issues related to GSYNC/FreeSync/VRR on some NVIDIA GPUs. The NVAPI profile was not being created which caused VRR to still be active for the app. This also appears to be a bug in NVIDIA’s GPU driver.
