Hi everyone,
I’m facing a strange viewport glitch in Unreal Engine 5.2.1, and it happens even in a blank project.
Issue description:
-
When I open a project, everything looks normal at first
-
After a few seconds, the mouse cursor disappears from the viewport
-
A weird visual glitch / distortion appears in the viewport
-
The glitch becomes visible when:
-
I hover the mouse over the top navigation bar
-
I hover over objects in the World Outliner
-
-
If I resize the Unreal window, the mouse cursor becomes visible again, but the glitch still remains
-
This happens even without Lumen/Nanite and in a blank project
System details:
-
Unreal Engine: 5.2.1
-
OS: Windows 11
-
GPU: NVIDIA GTX 1650 (4GB, laptop)
-
Driver: NVIDIA Studio Driver 536.67
-
Hybrid GPU system (Intel + NVIDIA)
I suspect this might be related to:
-
Hybrid GPU (Optimus)
-
Viewport resize / fullscreen / swapchain issue
-
Driver or Windows 11 compatibility problem
Has anyone faced a similar issue or found a proper fix?
Any help or guidance would be really appreciated.
Thanks in advance ![]()
If you want, I can also:
-
Make a shorter Discord version
-
Rewrite it for Epic Developer Community
-
Add steps to reproduce format (Epic likes that)
Just tell me ![]()
