i try to scale my old Win95 Game "Perry Rhodan Operation Eastside" to fullscreen - but since 16.9.1 its not possible anymore (havent tested 16.7.3)
with Sapphire Nitro+ RX 480 8G D5 OC
i also have "Desktop mousecursor"-Bug (have to use Windows Magnifier to fix it)
and then there is the "Fullscreen-Game no mousecursor"-Bug (but it think they have same Problem)
would be nice if you fix this too: Video Encode API: CBR with Filler Data does not meet minimum bitrate requirement. · Issue #18 · GPUOpen-LibrariesAndSDKs…
Please try updating your drivers to Crimson 16.9.2, using DDU to remove 16.9.1 and the corruption should be fixed.
What OS are you using?
