Ticket #5845 - Changing of the transparency parameter on Radeon GPU problem

Post by mnv »

Hi,

Has anyone tried to change the transparency parameter on last FreeCAD build?
Unfortunately, i got some problems with that on my PC with Radeon GPU.
This problem occured only on FreeCAD builds with Qt5.

Hi mnv, welcome to the forum.
The Radeon cards are known to cause problems. You may try to downgrade the driver: https://forum.freecadweb.org/viewtopic.php?f=3&t=30573.

Unfortunately, this problem is also occurred on old driver version.
I think this problem in porting to Qt5, because old FreeCAD versions and builded by hand FreeCAD version with Qt4 works fine.

So essentially it may be an upstream Qt5 issue?

I think this was determined ultimately to be an issue with COIN 4.0.0a (a being alpha?)

@mnv do you mind following up?
I'm closing issue #5845 for now. If the issue persists, you can ask for it to be re-opened
