There has been reported the following issue :

A customer experienced IDIS Center crash on their Demo Room PC when a camera pane is clicked and got into the full-screen mode.

After the crash, the IDIS Center window was disappeared but the G2Client.exe was not terminated and still alive in the Task Manager.

– There are two graphic adapters on our PC (Intel UHD Graphics 630 and NVIDIA GTX 1050) and we are using both adapters.

– Intel released a new device driver for Intel UHD Graphics 630 on 3/8/2019. Driver version: 25.20.100.6615

This issue has been caused after a Windows update.
and after restart the PC, the Crash issue has been started.
Then I rolled back the Intel UHD Graphics 630 driver to the previous one (which is version 22.20.16.4758, dated 8/2/2017)
Then it works without issue.

Solution:
Reason: Graphic card driver s/w bug.
H/W acceleration decoding of GPU is totally dependent on Intel device driver and implementation, and Client S/W is just interlocked only.
There have been several such issues in the past, all of which were problems with the Intel device driver.
IDIS Center is already using the latest version, so it’s not a version compatibility issue,
We have confirmed that the device driver released on a date similar to the problem-resolved device driver is also reproduced on Intel (R) HD Graphics 530.

We have checked that the latest device driver at this time, the problem did not occur,
If you use version “2019-05-28 / 26.20.100.6912” or higher, We think it will work properly.

No matter how Intel/MS, the device driver is just S/W, so there may be a bug.
If this happens, please upgrade your graphics card to a non-problematic graphics card to fix the problem.
