[Mac] Alt-tab and windowed mode cause display corruption

[tiborg]

Using window mode (cmd-f) to switch out of the app worked wonderfully under 1.30 but now it results in the games display becoming corrupted and unusable when switching back to the app. So now neither way of switching out of the app can be used.

Confirmed issues with the screen when issuing cmd-f. When I press cmd-f the screen just gets dark with some of the trees appearing and able to move like as if I was still in game. When pressing cmd-f a second time, the game comes back up as normal.

OK things changed in the meantime. I fixed some other mouse issues and it works in a window but obviously not with cmd-f. cmd-h by itself is worse, the desktop comes up but the monitor is still owned by the game so you see the game but can't access it.

What video cards are you folks running?

This is why having someone other than me use the app is useful :-0

EDIT: Yeah it sucks right now unless you like psychedelic art. Bug.

I couldn't even get Cmd-F to work yesterday in the full day Givet testing.

Nothing happened at all.

I will need to re-test to try Cmd-H, I wasn't aware of that key combo before this thread.

CMd-f no longer supported, using cmd-H or cmd-tab should hide the game.

Cmd-Tab worked, but my System Menu bar was invisible, and the cursor was invisible.

I could click and drag and see the selection rectangle, but no cursor. Because of this, I couldn't get my Dock to appear (it is auto-hide).

After I used Option-Arrow to go to a different Space, the menu, cursor and dock all behaved normally.

After that every time I Cmd-Tab back and forth everything was normal.

I then relaunched the game to test Cmd-H from scratch, and everything behaved normally.

There was, however, a LONG delay before another program would respond, and a lot of beachballing going on. And everytime I launched or accessed a new program, it was slow. I assume it was RAM being freed up for other programs to use.

Hmm Spaces, I guess I should try that. I have the same box and without spaces it works correctly. How did you get a 4870 with 1GB of vram?

Yes with 3GB of ran its likely all your other apps were swapped out. I have 8GB. Plus with the larger display the vram could be swapped out as well.

eBay, PC card flashed by a guy with really high feedback & ratings, 30 day unconditional refund.

It was 1/2 way between the cost of a Mac-native card and a PC card, and 30 days shoud be enough time to see if it was a lemon or not, so I figured, what the hey?

By the way, 3 GB is plenty for our game, right? Is there anything to be gained by adding more?

Thanks,

A minimum!

4gb better.

I have 3, and I am paging out quite a bit

[AHWULF]

3GB including the operating system, the finder and the clutter leak (still being fixed) you'd be safer having 4GB or more. Note we have so many textures now some get paged back into RAM due to the mac opengl virtualization of textures (its kinda aggressive) so in essence they are backed up in the application memory space. On the PC they are backed in the OS space so you don't see them as readily as "part" of the application.

I've also noticed that Safari and the Finder (when you use cover flow) wind up caching a lot of stuff in ram and refuse to give it back. XCode is terrible as well, sometimes I have to actually reboot my 8GB mac just to clear the caches (this is under Snow Leopard). So the more RAM you have the better :-)

cc thx

Tested offline, cmd-h is working fine. Sometimes the mouse cursor is still visible when I return to the game, but pressing option turns it off.

Wulf, what should I do with this ticket?
