Weird screen blinking.

[Rind]

Some time ago, before the final release of Regnum, once there was an update, that made my game blinking. After logging through rolauncher, main screen appeared but the refresh rate of that screen was so low that I could see stripes and white bars floating on the whole screen, and the game was unplayable.

Now I was trying to run Regnum again (on new system btw), but this problem still exists.

My O.S.: Kubuntu Feisty 7.04,
Graphic Card: Nvidia Geforce 2 Mx/400
CPU: 32bit, it doesn't matter which one, isn't it? :)
Xserver: Xorg, runs at 16bit (and I don't want to change it to 24bit)

I do have installed graphic card drivers, opengl runs smoothly, all the tests are ok.

The error log shows me just that I don't have an openal library but it is connected with sound, not with the graphics.

What should I do to make the game playable?

Greetings!

Can you take a screenshot? It would be very useful to see the problem.

[Rind]

surak, on every screenshot I took there was no blinking problem, but it is explainable :P it is just refresh rate is very very low, and the 'refreshing' of screen is visible, I mean that I can see that the frame/screen/menu things is currently drawing. Of course it is very very fast, but it is visible. I tried different types of options, different resolution, but the problem is still...

Can you check in your log.txt file (located in live/ subdirectory) for an entry like this, and post it?

And I want to say that the problem occurred after Regnum update, not my system update.

[surak]

Have you tried safe-mode?

[Rind]

Have you tried safe-mode?
Yes I have, coincidently, I always run Regnum at safe-mode :smile:, but not running in this mode also makes that blinking.

[Rind]

I was able to do some screenshots, here are four captures done one after another that shows the problem. The screen now should be the one with downloading resources, while it blinks very quickly so I can see my character (not the whole though) and the screen changes very quickly to another perspective which is a dark screen with nothing in it, or a broken graphics.

Hmm.... maybe Regnum can't find a double-buffer visual.

Can you post your glxinfo output? Thanks

It seems that there is no problem with 24bit color depth, but I would really rather be able to run the game in 16bit color depth.

[surak]

It's what I thought. Regnum is creating the window without double buffering, so you can see the scene redrawing. I am taking note of this issue for the next update.

Great :) Thanks a lot. After an update I will tell if it works. :beerchug:

[surak]

Should be fixed now!

[Rind]

Yes, now it works perfectly :D
Very very thank you, surak :beerchug: :beerchug:
