Using the latest update (same with the last two updates though). I am getting serious brush lag - like unusable levels of lag - when painting on layers that are inside of groups. That seems to be the common thread, but sometimes it happens and sometimes it doesnt so I can't pin down if it is any specific contents.
I'll have a layer inside a group, but at the top of the stack inside the group, and get crazy lag. If just move the layer outside the group, but still in the same relative position in the layer stack, the lag disappears. I have never had this happen before so no clue.
I disabled the GPU stuff and also toggled on "legacy compositing" but they did not help.
Any known bugs on this?
