[PATCH v2 1/1] user32/tests: Register test_hvredraw class in temp desktop.

[Marvin]

Hi,

It looks like your patch introduced the new failures shown below.
Please investigate and fix them before resubmitting your patch.
If they are not new, fixing them anyway would help a lot. Otherwise
please ask for the known failures list to be updated.

3 TestBot errors prevented a full analysis of your patch.
If the test caused the operating system (e.g. Windows) to crash or
reboot you will probably have to modify it to avoid that.
Other issues should be reported to the TestBot administrators.

The full results can be found at:
https://testbot.winehq.org/JobDetails.pl?Key=151879

Your paranoid android.
