Ugly desktop after quit a game with new xfwm4 improvements


Description Mike Massonnet editbugs 2006-06-16 19:59:40 CEST

With the last improvements in compositor I get an ugly desktop when I leave a fullscreen game.  Start xmoto for example, play a game, quit. Same with armagetron (play it :>)...

Drop-shadows will most of the time look black and moving a window all over the black or changing the workspace will, fortunately, redraw the content.

My guess would be to "redraw something" (/me knows nothing about wm :) after coming back from an "unredirected fullscreen override" window.

Should be fixed with rev. 22143; can you try?
Comment 4 Mike Massonnet editbugs 2006-06-18 12:37:04 CEST
It's working.  But now there is a bug with some panel plugins which are drawn opaque (systray, orage clock, clipman, system/net load, verve, ... sounds like external plugins only).  Mouse over the panel when it changes its opacity or right click on the plugins helps to get them back transparent.

I don't think we can fix that.
Comment 6 Mike Massonnet editbugs 2006-06-18 23:42:59 CEST
It's better than none synced displays, so, we should just change the resolution to fixed.

After exiting an SDL full-screen program...

I'm seeing something similar to this, but triggered by changeset 22143: the upper left area of the display (of a size which matches that of the recently-left screen mode) has correct transparency. Much, but by no means all, of the rest has none whatsoever - at least, in window content; frames are correctly rendered. This is transient, with correction occurring on redraw.

AFAICS, only SDL-based programs trigger this, but those which I've tried don't represent a good sample. (enigma will trigger it.)

Restoring the !WIN_IS_REDIRECTED check in fix_region() partially works: but two of three xfce4-panel windows become invisible, and tests with a third (framed) window - I picked a settings manager window - show that windows which are outside the upper left area become temporarily invisible.

Problem comes from games that render fullscreen *while* changing the screen size (typically games).

I don't see this with the latest builds though.

Bug #1930
