Ghosting dynamic lighting

1692039448

Edited 1692039511
If I have dynamic lighting turned off, I can move the map around, change the scale, etc with no issues. However, I'm noticing new behavior (new as of Sunday for me) where, if a map has UDL, and I scroll the map, every time, it creates a ghost image of my map.  If I simply click on the GM layer, then back on the token layer, it clears up.  Suggestions?

Hi Wyrmwood,  Which browser are you using?  Does the problem persist in an Incognito (Chrome) or Private (Firefox) window?

Not a solution, but perhaps an avenue of investigation: Are you using explorer mode? If so, have you tried deleting the cache? Explorer mode is the only thing I can think of offhand that serves up two map layer renders.
If you change the map on the map layer after drawing the dl lines on the dl layer, the dl lines will stay in place and do NOT update with your map changes....

Dah! I spoke too soon. That got rid of the ghost image, but when I move the map, I still end up with doors (and probably walls) that don't match the image.  It appears that the image is off, as when I click on the map or lighting layer, the map moves, but not the doors. Strange.  Also, from previous comments, browser is Chrome 115.0.5790.171, yes, tried in incognito. Even when it is working properly, when I drag the map, I can see it drags the doors first, then the image catches up. When this error occurs, the image does not "catch up", but you can force it to by changing map layers.

Just to clarify, when you say "drag the map", do you mean reposition the image, or panning? Something went awry with the screen shot you posted. I'm assuming panning, since maps and DL are not linked in any way. Does this happen with other maps, or just this one? I believe you said in a different thread that you are using the VTT importer script. Does this behavior exhibit itself on manually edited pages?
OK, I figured out the problem. I can't remember where I read this, but something told me to use Vulkan with AMD. That not only caused this ghosting problem, but also several other issues with Chrome + video. I disabled #enable-vulkan in chrome://flags  and it seems to be working again.  Yes, by "drag the map" I mean right click and drag the mouse, I guess technically panning the view port, but it sure feels like I'm dragging the map, since the view port doesn't move.
