Mad Mapper Full Screen Freezing
Posted: Fri Oct 03, 2025 7:26 pm
Hi All,
I've been running into an issue when running MadMapper 5.6.7 on my Optoma ZK810TST for a 24/7 install.
We are using it to project an Unreal Game screen through Spout OBS onto an exhibit wall. For some reason (seemingly at random), when running in Full Screen mode, the projected image randomly freezes. The weird thing is everything is running as normal. The Mad Mapper preview shows the correct image updating, the game is running without issue, and it is fixed by simply deactivating and activating full screen mode. I can even see any screen I drag onto the projector display, the only thing frozen is the Mad Mapper full screen view. I've already checked and there's no GPU errors logged, and it can happen when nothing fancy is happening on the projected screen.
After checking the Mad Mapper logs, this is what I find:
"Error in D3D output, lock D3D render Target View: Unknown error 0xC00700A7
