Description Pierre Ossman cendio 2016-10-19 13:12:16 CEST
Resizing the session almost works. The session dimensions are changed, as are the rdesktop window dimension. However the graphics are only updated in the area of the original size. The rest remain black.

Tested with 4.7.0rc2 and 4.6.0 on SLES 12.

Works fine with Windows 2003 R2.

We need more information here. We should test on more distributions, older ThinLinc versions and more Windows versions.

Works fine with nightly build 5273 against marina.thinlinc.com (2008 R2 standard), running on CentOS 6.

Using same TL server, connecting to Windows 2012R2 server in admin mode: Still works fine.

Note that MS introduced support for changing session size without reconnect in Windows 2012 R2:

This seems to be related to Windows Updates. When WU said that I had 226 pending updates, it worked correctly. After installing a few of them (196 remaining), the problem happens.

It seems the problem starts for me after installing https://support.microsoft.com/en-us/kb/2934520, which is strange.

Uninstalling this update does not seem to fix the problem.

Reverting the Windows 2012 r2 snapshot back to when it was created in 2013 still shows this problem.
