Bug 2817

Summary: SDL_RenderPresent() demands attention?
Product: SDL Reporter: Thomas Vesper <thomas.vesper>
Component: *don't know*Assignee: Ryan C. Gordon <icculus>

Description Thomas Vesper 2014-12-12 09:30:40 UTC 
Under certain conditions _NET_WM_STATE_DEMANDS_ATTENTION gets set.
Depending on WM preferences this causes different kinds of annoyance.

When I first noticed this behavior the SDL-window followed me over all desktops.

A simple loop using a renderer is enough.
(e.g. http://lazyfoo.net/tutorials/SDL/07_texture_loading_and_rendering/index.php)

When I switch workspaces or move the window between workspaces the attention flag gets
set most of the time.
(xwininfo -wm => Window state: Demands Attention)

It doesn't happen without renderer (like http://lazyfoo.net/tutorials/SDL/01_hello_SDL/index2.php)
It doesn't happen with any other program I know of.

I watched this under XFCE 4.8 (debian/wheezy) and XFCE 4.10 (debian/jessie).
KDE 4.4.5 on debian/squeeze seems unaffected.

It seems to make difference if I switch workspaces via keyboard shortcut or by clicking on the pager widget.
