Hi Michael,

I just logged a similar bug for version 1.8, however it does not happen during painting anymore. For a lot of filters we do not let the user know the program is doing something, we should fix this.

The other thing is, that in the latest version, the program does not become unresponsive, however it crashes at that point in the code (I think). See bug report with stack traces. I think this is a threading issue, but should not be hard to fix.

Can you give fixing the bug during painting highest priority, as with the old version it hangs and with the latest version it crashes, it should not be hard to fix it. The crash is in the function glIsTexture, probably we assigning it a zero pointer.

best,

Jeroen

I am successfully running SCIRun 3.0.2 with an nvidia 7600 GT without
any problems on Kubuntu.

When I try to use the Seg3D powerapp, I get frequent and slow screen
refreshes which make it unusable. It stops completely if I move the
mouse off the window, but then I obviously can't interact with the
program.

Has this been seen by anyone else? Any fixes? Is there some kind of
event that my window manager is sending the program which is causing
it?

Thanks,

ian
