The problem with the interface when a remote connection via RDP

Tested on version 4.5.8 (2500) and 4.5.9 (2525).

OS: Windows 7 SP1 x64
Video: Intel (R) G41 Express Chipset

When running PsPad when switching from locally on RDP or RDP on locally, the interface is drawn in part. And high CPU usage (1 core of 4).
After restarting the operating normally.

Screenshots attached.

Thanks in advance.

Please write step by step what should I do to simulate it.

1. Start PsPad.
2. Minimize PsPad.
3. Connected to this PC from another PC via RDP.
4. Work in PsPad (50/50 operating normally)
5. Minimize PsPad.
6. Logged locally on the PC running the PsPad.
7. Got problems described above.

Checked on another PC, the problem is not found. Perhaps this is a problem specific configuration PC. I'll try to update the driver and repeat the test. I will write later about the results.

Let me know please after your tests. Than more exact will be your description and I will be able to simulate it, than faster I can fix it.
