Steps to reproduce
Start an xrdp session at least one monitor has more than 4096 pixels wide or high.
We can start an RDP session larger than the physical monitor if specifying width/height via command line options.
- Press Win+R shortcut key
- Run
mstsc /w:4160 /h:2160 /v:xrdp-server.example.comto specify screen - Login with valid credentials
✔️ Expected Behavior
Works fine as well if the width or height is less than or equal to 4096 pixels.
❌ Actual Behavior
No response
Anything else?
This issue is similar to #2063 but there's no protocol error. #2063 happens if the total screen width is more than 8192. However, this issue happens when one of the monitors has a width of more than 4096.
