hi guys, I’m with latest RC 1.3 and I still got the problem about IR doesn’t works with material/map navigator opened, just regarding this thread https://forum.corona-renderer.com/index.php/topic,8780.msg57098.html#msg57098 was moved to resolved bugs board months ago.
check the video.
Confirmed. Looks like IR and navigator are fighting each other.
Also, I get a complete freeze after enabling thumbnails in the navigator window (even if IR is not running!) - I made minidumps but they are >200mb.
Generally it looks like there is conflict between rendering of navigator previews and IR and they go into a loop disturbing each other.
also checked with “enable material editor” on/off, no change
i cannot reproduce it, have you tried it with the non-legacy browser?
Ondrej, unless we are just using different words, this is not about the browser, but about navigator - as shown on the video. The icon with a “tree” of materials on the right side of meditor. And some materials (maybe with maps?) must be added.
sorry for non complete info from the video I made, here it is the screenshot of material/map navigator icon
ok thanks, I can reproduce it now. I am not sure I will be able to fix it before 1.3 - it will require some non-trivial changes in the way IR listens to the scene.
soo… our oldest active bug report should be fixed in v3 
Confirmed. It’s been fixed.
great news, thanks!
