[How to change default size of the color picker in Affinity Photo]

Would also like to see this. Or even staying selected while the program is open. I usually go with 17x17 and have to select it every time I open a new image in a tab.

[Way to set default JPEG export quality?]

Thanks so much, it seemed so random across my various computers! I never noticed or thought about the preset selection. Make a new preset to the JPG quality you normally use. Save something with that preset and now it will be retained through open/close of program.

 

[Affinity Photo 1.9 Slow with OpenCL enabled]

Came here looking to see if others were having the same problem. Glad to see not just me. Affinity Photo is laggy with the OpenCL option enabled. Using something like the clone brush tool, the image update lags behind the brush cursor. I have turned off OpenCL acceleration. It's not a big deal, the program was plenty responsive enough before the option, so I just disabled it on my Windows installs. But it was the only reason I upgraded to version 1.9 (and went through the Windows updates to get the new feature available).

I'm perfectly happy with the performance with the option turned off, but just wanted to add more data points.
