Steps of reproduction

1. Build the latest version of your picom fork.
2. Install and run with --experimental-backends.

Expected behavior

Fading works like normal, and so does the animations.

Current Behavior

Animations do not work half the time, and nor does fading, which used to work just fine.

Stack trace

Doesn't crash.

[jonaburg]

You'll have to increase your fade-delta most likely. This fork uses the same float for fading as it does the animations, which have now been reduced to microseconds depending on your cpu clock. I may separate this into another variable in an upcoming commit, so it's at least separate from the fading calculations, so that others don't have to deal with changing their default fade-delta values.

Also, play around with the transition-length and transition-pow-(x/y/w/h) values representing length and animation smoothing, you may have better mileage by tweaking them. Can you please explain what happens when you adjust these values?

[notsatvrn]

When I adjust the fade delta, it appears to have no affect on the animations. I will try the transition variables right now, and report back if I find a difference.

[notsatvrn]

Nope, still nothing.

[jonaburg]

are there any noticable differences if you try to run it with the xrender backend vs glx?

[notsatvrn]

Nope, and xrender is very laggy.

[jonaburg]

Strange. Can you please clearly explain where you are at right now? You mention: Animations do not work half the time, and nor does fading, which used to work just fine.

After adjusting the fade delta, you confirm it has no effect on the animations, but can you provide if it reverts issues with the fading back to what you would expect? In addition to this, you mention that the animations don't work half the time. Could you please explain what this means, in what capacity, and in what kind of 'lagginess' do you feel? Is there any spike in CPU usage during this lagginess?

[notsatvrn]

It does revert the fading back to normal. The animations worked once, and only once. And when using xrender, the mouse doesn't move properly, and it looks like its running below my monitors refresh rate.

[unai-ndz]

I also have an R7 250 so I felt like testing your config.

I can't reproduce the issues you mention besides xrender being laggy which stops happening if I turn off the blur. (This happens in both this fork and in the original picom mind you.)

I use the amdgpu driver which maybe makes a difference. I think radeon is the default for this card. You can check which one you are using with: lspci -k | grep -EA3 'VGA|3D|Display'. Feel free to ping me if you want more details about my setup.

[notsatvrn]

I ended up not using this fork and got an RX 570 recently. I use amdgpu because of Vulkan support so using radeon would be out of the question.
