Bug#1001626: enlightenment: Starting gkrellm or qmmp, enlightenment process takes too much cpu cycles

[Adrian Immanuel Kiess]

Dear Ross,

thank you for your answer.

I talked to raster at the #e IRC-channel.

The cause seems to be the shaped windows, like gkrellm owns.

He suggested, I should change the default gkrellm theme.

This worked fine for a locally running gkrellm.

When using remote GTK applications over SSH, the shaped windows of my
current GTK seems to be the issue.

In addition to that, what also adds to the cause is the connection to
my virtual private server using SSH. Using another network connection to
a local VM, the issue is not present.

To fix this, I think I'll need faster hardware then. 

You can close this bug-report.

Thank you for your kind help.

Sincerely,

Adrian
