high GPU load when selection is active

[rpnfan]

1. Create a document in Photo (raster)

2. Ctrl-A (select all)

→ GPU load will rise to about 50 to 60 % just for the selection being active and doing nothing. The GPU load will not fall down until the selection is cancelled.

What GPU do you have? The marching ants cause the document view to refresh, so some increased GPU usage is to be expected.

I just found that there seems to be a "GPU-leak". I had a small document, where I replaced the colors with another color. The operation was finished, but still both GPUs are maxed out. This is very annoying as the computer runs much hotter than as needed with a reduced life-time and the fan running at full speed to counter the heat generation, which is also noisy btw.

I saved the document. After reopening the document and doing "nothing" the GPU stays low. Because I just made a very simple operation, which was finished and _no_ selection was active the GPU load should have also been low / non-existent -- which was not the case. 😞

I attach the document, although I fear that won't help directly. But you can at least see which operation was carried out (selection done, adjustment layer added and color converted, selection deleted, PNG exported) -- which left the GPU load high. 😮

Thanks for the file. I loaded it up, made a pixel selection, saw the GPU usage rise to 20%, then I deselected, and noticed the usage drop to 0%. If you leave your document for a few minutes, does it eventually drop the GPU usage?

No, the GPU load was there after a longer time, maybe 20 minutes or half an hour or even longer. I had done the operations described above and then continued with other work, forgetting that Affinity Photo was still open in the background, till the fan was getting on my nerves and I looked for the cause.

My second report is not related directly to the first one -- or at least it's not clear if it is. First case: "selection" causes high GPU load, second case: steps carried out described led also to a high GPU load which was not falling of after a while... 😞 I was not able to reproduce that, therefore my statement about some kind memory-leak like GPU "leak".

Hello there,

Meet the same issue, active selection will load the GPU and make it noisy.

My UPS show a power consumption raise from 250~240W to 390~400W.
Deselecting will drop instantly power usage.

This is quite huge for a simple animation :)

Problem is still not fixed in latest version... 😞
