Hey guys, just popping back in to confirm that this is still an issue with the current stable release. Disabling V-sync in Catalyst resolves it, but every time I update Construct, it starts happening again.
This is probably because updating Construct uninstalls the previous version, which deletes any custom application settings in Catalyst. So, each time a new version of Construct is released, I have to remember to disable v-sync again.
Yes, I realize that the problem is probably on AMD's end, but somehow I doubt they'll fix it any time soon.
