I have also reported this in the wine bugzilla here: http://bugs.winehq.org/show_bug.cgi?id=21327 do you use Desktop FX and does the problem persist when suspending* them before running the game? *press ALT+SHIFT+F12 Effects are already disabled in systemsettings->desktop just to be sure then: you don't use any kind of compositing (neither kwin desktop FX not compmgr) yet the game window is really in the foreground (updates content), BUT clicks are passed through to the windows beneath? can you open rmb contextmenus (e.g. for konqueror, but by clicking into the game) and do they appear on top of the game window then? (and what game btw?) I disabled all effects because the graphics card isn't really all that powerful ~/.kde4/share/config/kwinrc says: [Compositing] Enabled=false [...] and i'm not using compiz or anything either. the effect is independent from the game, the games that i tested are "Siedler 2: Die Nächste Generation", "Civilization IV" and "SimCity 4" when i right-click to open a context menu it draws the correct windows and the context menu for a short time, and then it redraws everything with the game (it does not show the context menu above the game) it sounds like a wine issue to me. Unfortunately I don't have wine installed or any Windows Game to test with. i've none of those games, but it sounds as if "wine -> d3d -> gl" paints into an overlay and that is broken on that particular driver/gpu and (under certain conditions) paints unclipped into the framebuffer. this may be related to Option "OpenGLOverlay" "1" # or "0" in xorg.conf (which will however disable/enable xv acceleration) I've tested with - Jedi Academy (opengl game) -> can't alt + tab out of it. The game looses focus but stays on top. - Maniac Mansion deluxe -> acts "normal", ie. i can alt+tab around. - nvidia's dawn demo (pseudo fullscreen) -> just like MMD is this still an issue? yes, this still occurs with newer hardware and newer driver. i also could produce problematic results with setting kaffeine/xine to OpenGL mode (instead of xv) To make that clear: what you observe is an issue of the GPU's framebuffer/overlay handling. I assume it will not happen if you
a) enable compositing
b) keep it enabled
c) do NOT suspend compositing for fullscreen windows (3rd tab of "kcmshell4 kwincompositing")
This has however a performance impact and you likely don't want to do that when gaming (you want to completely suspend compositing before to have all resources open for the game, there's also a rule to automatically do that when such window appears)
The only thing kwin could effectively do in this regard was to disable alt+tab for fullscreen windows in general (what's very much likely just a "no-go")
What you could to is to setup a rule for that wine window to ignore global shortcuts ("kcmshell4 kwinrules", you can likely utilize the detection delay)
Have you ever tried the xorg radeon driver?
(In reply to comment #10) > Have you ever tried the xorg radeon driver? sporadically. but last time i had overheating problems beacuse some energy saving features failed to trigger, and in general behaviour was IMHO worse. so i decided to not try that any time soon, and rather live with this behaviour. |
