Ruler causing cursor lag

[Spiral_Head]

Hi there, I've recently noticed that when using any Affinity programs on my G-Sync monitor the cursor lags/hitches while passing over the ruler and other pieces of the UI only when the ruler is shown. Hiding the ruler eliminates all lag/hitching. The lag is not present on non-G-Sync monitors, or when G-sync is disabled, however when G-Sync is disabled screen flickering becomes present when mousing over the UI elements. As discussed in previous forum topics, switching the renderer from my GPU to WARP resolves the issue. Disabling hardware acceleration does not resolve the issue while my GPU is set as the renderer.

My PC specs are as follows:

CPU: Ryzen 3900x

GPU: RTX 2080 Super

RAM: 16GB DDR4 @ 3200MHz 

Monitor: 2560x1440 144Hz G-Sync (Acer XB270HU)

Using all the latest drivers and non-beta software.

Perhaps you have Nahimic installed?

Did you check the runnig Services in Windows?

If not, please click the Windows Start button and type Services, then click on the Services app in the result list. Scan the list for Nahimic.

I didn't check there originally, but after checking the list I'm not seeing it

OK. Part of your description is quite similar to what it causes for some users. Thanks for checking.
