Chromebook Linux (Beta) with Eclipse installed - GUI flickering

Let's make sure issue is not already fixed in latest builds first.

• I verified I can reproduce this issue against latest Integration Build of Eclipse SDK

Steps to reproduce

From a fresh installation and clean workspace:

• enable developer mode on Chromebook
• install Eclipse
  • d/l Eclipse installer from https://www.eclipse.org/downloads/packages/installer for Linux x86_64
  • extract contents, tar -xf <file_name>
  • run ./eclipse-installer/eclipse-inst to install Eclipse
  • launch Eclipse or run ~$ ./eclipse/jee-2024-03/eclipse/eclipse

I tried

• *mouse over hyperlinks in Project Explorer view with no projects
• *as mouse pointer moves, hyperlinks start to flicker in the view, this is exaggerated when working with Eclipse as projects are added, files opened, entire views start flickering.

I expected: stable fonts

But got: random flickering fonts

Here is some relevant log output

From <workspace>/.metadata/.log

• opened an issue with Chromebook help, one of the responses is,"We've found that some apps may not play nice with the Wayland display compositor used with the Linux Development Environment. "

Community

• I understand reporting an issue to this OSS project does not mandate anyone to fix it. Other contributors may consider the issue, or not, at their own convenience. The most efficient way to get it fixed is that I fix it myself and contribute it back as a good quality patch to the project.
