I use SAS for Linux. Its windowing system uses Motif/X11. In 42.1 it worked fine. In 42.2, the windowing system will not clear text. Backspace and clear act as if the text is gone, but instead leave it and when advancing past a given letter add an underscore. After backspacing, new text simply overwrites the existing text without erasing it making it unreadable. I’m thinking there is some package I need that I haven’t installed. The Motif/X11 information SAS supplies is:
OSF/Motif release is 2.3.3
Xlib release is X11R6
X server release is 11803000.
In 42.1, this is the same, but the XServer release is 11702000.
Any help would be greatly appreciated - this is an absolutely essential package for me.
I found the root of the problem. It is with the radeon driver. I popped in an Nvidia video card and the problem disappeared. To confirm it was the driver and not the hardware, I found I had the issue using both the onboard R7 chip and an external R7 card with the onboard video chip disabled. I never had this problem in 42.1 using either the radeon driver or fglrx, so there is some issue with the interaction of the AMD drivers and the system. While SAS is probably a little bit esoteric as software, I wouldn’t be surprised at all if this problem doesn’t crop up in other applications that write to the video buffer using the same method as SAS.
My guess is that someone will take a look at whether what you’re obverving has anything to do with how openSUSE compiles its kernel, then possibly pass it upstream for inspection.
Be sure to include detailed description of your hardware, display driver and your findings.
