Created attachment 286987 [details] screenshot 1 # Context I had previously opened an issue against PDT: https://github.com/eclipse/pdt/issues/113 But I was able to reproduce this with other unrelated editors too. # Description The vertical line number region sporadically exhibits garbled or duplicated text. This is only reproducible on Wayland sessions. I have tested it on Ubuntu 21.04 and Fedora Workstation 34 using the GNOME desktop. # Steps to reproduce 1. Open a file that is long enough to scroll through it 2. Keep scrolling up and down (with the mouse wheel or touchpad) until the line numbers become garbled. Scrolling any further from that point might trigger a new render that eliminates the glitch. # Environment Eclipse 2021-06 Ubuntu 21.04 amd64 (ubuntu (GNOME) session on Wayland) One potentially problematic component here is the graphics card: AMD RX 560 (amdgpu). Any other details, just ask.

Please try with latest 4.21 M3 build https://download.eclipse.org/eclipse/downloads/drops4/I20210823-0600 and with a default (not dark) theme. Please also provide all SWT related config data from Help -> About -> Installation details -> Configuration (filter for org.eclipse.swt.)

Created attachment 287089 [details] screen recording with a newer eclipse build (In reply to Andrey Loskutov from comment #3) > Please try with latest 4.21 M3 build > https://download.eclipse.org/eclipse/downloads/drops4/I20210823-0600 I have downloaded an archive named "eclipse-platform-I20210823-0600-linux-gtk-x86_64.tar.gz", is that the right one? I can reproduce the bug with this build. I'm attaching a screen recording so you can see what I see.
Let me add some observations: 1. Scrolling _up_ doesn't trigger the problem, only scrolling _down_. 2. Scrolling by dragging the scroll bar doesn't trigger the problem, only scrolling with the mouse wheel does it.
I have been having the same issue for quite a while. Ubuntu 23.10, Eclipse 2023-09. Seems to more easily repeat itself it I scroll up and down quickly. Doesn't seem like this bug has been updated in a while but is definitely still a bug for me.

FWIW, project development moved to https://github.com/eclipse-platform/eclipse.platform.swt and this one will not get any attention here.
