Konsole issue

Hello. After being on Ubuntu 14.1 LTS for years, I tried to update to 16.1. Install media Would. Not. See. workstation's RAID so switched to CentOS 7 (all my production stuff uses that anyway). Immediately installed TDE, of course, 14.04 I think. Two issues with Konsole, possibly related to the video driver (card is an "AMD FirePro V4900" with their drivers). First is that it seems to have trouble rendering the _ (underbar) character. No problem leaving random underbars on the screen as text advances, but can't seem to put them in the right spot. This is most noticeable on the last line of a screen full of text. Second, and much more annoying is that when I start Chrome (not my primary browser but necessary for some sites), Konsole becomes very sluggish. Not 2400-baud modem slow, but that was the first thing I thought of. Maybe more like 9600 ... or 14.4 ... Ideas? I do run yum update regularly. -- Peter Laws, BS, MRCP / N5UWY National Weather Center / Network Operations Center University of Oklahoma Information Technology plaws(a)ou.edu
