[0.11.22] window matching woes

[prg]

I'm trying to match the Factorio window on Linux to move/resize/undecorate it, but initially it doesn't have WM_CLASS and WM_NAME properties, those only get set later to "Factorio $VERSION" so I had to add a hack to devilspie2 to attempt the matching again after a second if class and name come up empty. This kinda works but is not very nice. Could you set those properties before mapping the window?

Hey did you accidentally fix this? On 0.12 WM_CLASS now seems to be already set when the window is opened. This isn't due to a change on my end since I can still reproduce the described behaviour with 0.11.
