Does this happen every time you log in to KDE, or just sometimes? Can you try running KWin with EGL? KWIN_OPENGL_INTERFACE=egl kwin --replace That may help. It does occur every time I log into KDE and try to play some games (not often -- I usually use i3 when I decide to play a game now).
I tried:
KWIN_OPENGL_INTERFACE=egl kwin --replace
but it did not change anything.
I have noticed that the game window seems to "add" to the background.
Example (with black background):
#000000 (Black)
#ff0000 (Red)
-------
#ff0000 (Red)
Example (with white background):
#ffff00 (Yellow)
#0000ff (Blue)
------- (White)
#ffffff
Note: This is what seems to be happening -- if the background is yellow, then the window will have a definate yellow color. Same from any color besides black.
Okay, thanks for the information. I haven't seen this before, and it looks distinct from the other bugs a lot of people are hitting. We'll have to look into it further... A recent update to Arch has fixed this issue. I'll take a look at Fedora Rawhide and Ubuntu 14.04 to see if they work now as well. Thanks, Taylor As of 26 April, 2014, Fedora Rawhide still has this issue. I tested in both KDE and GNOME. When I looked at Ubuntu 14.04, Unity seemed to work. In that case, I suspect the bug is actually in the X server. Rawhide ships with xserver 1.15.0, which has a known GLX bug that can give you random visuals. (Perhaps it's giving you one where the alpha channel results in window transparency.) Arch Linux ships 1.15.1, which fixes that bug. Sorry we never managed to look at this. I think it got fixed a long time ago - I've certainly not heard of this happening in a long time. If you're still having issues, feel free to file a new bug. |
