Testing DP mode, this display mode can't show correctly, I have attached a photograph to show the phenomenon. Each Command below can cause this issue. 

./testdisplay -d 24
./testdisplay -p 100,100,0,0,200,200
./testdisplay -t

- Is the distorted output stable or does the image also flicker?
- The backtrace is missing important information at the top, please reproduce the issue and ensure nothing is cut off when attaching a new dmesg.
