Workaround: Disabling "Edit->Preferences->Performance->Enable OpenCL compute acceleration" seems to fix the issue. So there is a viable workaround.

When selecting the Affinity Designer window, the framerate seems to gradually slow down over 10-20 seconds. The mouse moves less smoothly, eventually jumping in small increments. It feels like 10-20fps at worst. Affinity Designer itself also seems to operate more slowly, with more graphical artifacts etc. Clicking outside Affinity Designer instantly makes the mouse cursor move smoothly again(100fps, which is G-Sync max for my monitor.) Clicking back inside Affinity Designer begins the slowdown process anew.

The currently opened afdesign document does not appear to matter. It's a general issue.

Specs:
GPU: Nvidia GeForce GTX 3090
Nvidia driver: 472.12 (A bit older, needed for 90Hz on Pimax8kx. Could be relevant.)
CPU: AMD Ryzen 9 5900X
Monitor: ROG PG348...
Resolution: 3440x1440@100Hz, G-Sync (Fullscreen and Windowed. Tried fidling with this. Had no effect.)
Affinity Designer's resolution: 1600x1000ish, not fullscreen.

Hi Pumpkin,

Welcome to the forums :)

I'm sorry to hear you are experiencing performance issues with the app. Please could you try disabling G-sync to see if this issues persists? If possible could you also provide a screen recording showing the slow down. If you open task manager does the CPU etc usage go up at all when the app begins to slow down?

Thanks

I have been trying to recreate the issue for the past hour now, and I cannot for the life of me get it to happen.

I've enabled disabled G-sync, as well as set it to fullscreen/windowed.

Enabled OpenCL compute acceleration.

And a whole bunch of other things that had no effect. All driver versions are the same. Affinity is the same version. Nothing should be different.

It's running perfectly smooth no matter what I do. Which is good, obviously, but it's also driving me crazy.

The only conceivable difference I can think of now is that I have plugged in a second monitor that's running at 60Hz. And I have unplugged a wacom tablet. But I have to run, so I'll have to try that theory later.
