Blinking wallpapers

[Better Half]

I don't have slideshow on or anything. I've tried switching over to my geforce card, but the wallpaper still blinks. I'm starting to think it might be a certain animation that does it. This is the wallpaper. https://steamcommunity.com/sharedfiles/filedetails/?id=1220364982

Is it the only one that does that? I don't see any blinking, there is only a small lightning flash in the top right. Could you perhaps take a video?

This is my desktop and it happens around the 13 second mark.
Also it's not only this but I've had this problem in a few other wallpapers as well.
Edit: paste the video into a browser it's just a black screen for some reasons on steam

I get something similar. Only mine stutters. And by stutter I mean has a straight up seizure.

Which graphics card models do you have exactly? And does this happen with any of the stock wallpapers?

Could you download this test project and put it into wallpaper_engine/projects/myprojects, then open it as a wallpaper? https://www.dropbox.com/s/chku1fbwo6v8mjk/shake_shader_test.zip?dl=0

If this also blinks then I likely know what is wrong.

Yes this blinks and black rings flash on the screen as well. My card is a GTX 960

Thanks, I changed something, could you download this and check again: https://www.dropbox.com/s/4zltuha9n0jyzkp/shake_shader_test.zip?dl=0 ?

This one works.

Thanks, and do you have a GTX 960 or a GTX 960m?

I'm afraid this issue is thanks to some unknown weird math optimizations that graphics card vendors do to get better performance... I thought only Intel was being finicky about it though. If you have a GTX 960 m then the program is actually using your Intel GPU, so that's why I was asking.

Unfortunately the wallpaper itself needs to get this fix by importing the "shake" effect again, I can't fix that wallpaper by only changing the program.

[Better Half]

Ok thanks, but what do you mean by importing the shake effect again? Now that you mention it it must be a GTX 960m, but I've already tried to switch over to it to test instead of using integrated graphics, which seemed to yield no difference.

If you run it through Steam it will switch back to Intel. You can change it in the Nvidia control panel to the GTX and then start it without Steam, it should work then if you do have a laptop with Intel/Nvidia: C:\Program Files (x86)\Steam\steamapps\common\wallpaper_engine\wallpaper32.exe

The creator of the wallpaper must add one of the effects (the 'shake' effect) to the wallpaper and it will apply the fix for the existing effects. This is the only way to fix that particular wallpaper.
