Hello everybody, the following error already occurs since version 1.x of Affinity Photo and was already described in connection with Affinity Designer 1.x in the respective forum and declared as a bug. My setup: Affinity Photo 2.0.3 Windows 10 Pro 22H2 64-Bit Windows settings: Windows HD Color --> Use HDR is disabled (but switching HDR does not seem to make a difference) Dell Alienware AW3432DW (3440x1440) running at 120 Hz (G-SYNC Ultimate enabled) (via DP) (one monitor setup) nVidia RTX 2080 nVidia studio driver 527.56 (latest version) Under these conditions, a slight flickering occurs when moving the mouse over the Affinity Photo window and when typing on the Affinity Photo window. When working over the window of another application or over the Windows desktop while Affinity Photo is open, no flickering occurs. From Serif, I only use Affinity Photo, but it is so far the only application I use that is affected by this behavior. It also doesn't matter if Affinity Photo's window is maximized, or only takes up part of the screen area. There are several workarounds described in the Affintiy Designer forum post. Some users find it helps to reduce the refresh rate to 60 Hz. For others, turning off G-SYNC seems to help. In my case, only turning off G-SYNC helps. I do not know, why in my case disabling G-SYNC was the only way to work around the flickering. Maybe it is because my display has a slightly higher width than the standard 1440p displays from the users describing that reducing the frame rate to 60 Hz had helped them. It also makes no difference whether G-SYNC is active in the graphics card driver only for full-screen applications or also for applications in windowed mode. As other users already mentioned I would rather not turn off G-SYNC or reduce the frame rate since I paid for these two features. But, still on one hand I do not know wether Affinity Photo or Windows or the driver is causing the issue. On the other hand the only application I am having issues with is Affinity Photo. I would be glad to help sorting out causes. If Serif needs more input they may text me.
