fullscreen games at lower than native resolution only show upper left corner

[David LaFreniere]

bug can be worked around by using gnome-fallback session or using unredirect fullscreen windows.

bug shows with both native and wine applications.

only happens when using compiz as window manager, others work as expected.

i've tested with the propriatary nvidia driver and the nouveau driver. bug also happens on my laptop with both the intel driver and the radeon one.

can also be reproduced with the livecd.

Do you mean you only see the upper left corner of the game covering the desktop, or the whole game fits into the upper left corner of the desktop?

[David LaFreniere (dlafreniere349)]

the upper left corner covering the desktop. sorry about being unclear

[Daniel van Vugt (vanvugt)]

I think I have seen this happen with OpenArena. Very strange because Compiz has nothing to do with resolution changes. It just adjusts itself when some other app changes the resolution.

[David LaFreniere (dlafreniere349)]

OpenArena is one of the games it affects. The higher the starting resolution is, the greater the effect. It looks like the game is being scaled to the prior resolution. If the game is at a higher resolution than the starting resolution, the game crashes. For games being run through wine, xrandr --auto seems to fix it.
