Have you tried running the installer and/or the application without
su-privileges?<br>
<br>

also appears only as a grey rectangle.</span></blockquote>
We have not tested Oxygen or the installer on CentOS 7, but the
problem you are experiencing (empty windows) seems to be between
Java and the X11 graphical system.<br>
Please check the version of Java being used, "java --version"<br>
<br>
I found an article about a similar problem with Intellij (also a
Java app) on CentOS:<br>
<a class="moz-txt-link-freetext" href="https://intellij-support.jetbrains.com/hc/en-us/community/posts/360000436304-Intellij-appears-as-a-blank-white-window-when-opened-on-Centos">https://intellij-support.jetbrains.com/hc/en-us/community/posts/360000436304-Intellij-appears-as-a-blank-white-window-when-opened-on-Centos</a><br>
If you are working remotely (e.g. via XRDP), check if the
framebuffer is configured to use 24-bit of color. <br>
Someone mentioned there that he resolved the problem in CentOS 7.6
by editing /etc/xrdp/xrdp.ini and changing max_bpp=24.<br>
<br>
If the problem persists, consider installing v21.1, OpenJDK
distribution, "<b>Linux 64-bit (Includes OpenJDK 12.0.1)</b>"?<br>
