Hi, I have a rendering problem in KDE Konsole terminal when using tmux with multiple panes. I’ve attached the photo because artifacts disappear when a screenshot is taken. Stripes appear after quick pane change or modifying large blocks in vim. They disappear after s second or two or after the next screen cursor movement. Their amount and placement are random. In general, it appears after operations in the terminal produce a lot of line changes. I’ve observed this effect only in Tmux inside Konsole emulator (I’ve checked on xterm and terminator and I haven’t noticed this effect). It worked well a month or two ago (I think I’ve updated Manjaro twice since then). I’ve read that it may be caused by screen scaling but I use 100%. It’s not making work impossible but it’s getting more and more annoying over time. One option is to switch terminal emulator but I like Konsole… Has anyone experienced something similar?
