IDEA and KDE empty popup windows

Does anybody else experiencing following problem with popup windows in IDEA 10.5 (also 10.0)?

Problem: When right-clicking on items (java class, directory, run configuration, ....) I get empty popup window. By empty I mean that it has slightly visible frame and no visible content.
When I use arrow keys I can navigate in popup menu, but selected what item I am on I can see only in status bar at the bottom of the window.
I am running Fedora 14 with KDE and Oracle JDK 1.6.0_27.

Any workaround to fix that?


Sometimes empty dialogs are a common Swing problem on Linux, even on Gnome.



Looks like I have found the solution for KDE 4.6.5 (Fedora 14).

Go to your Desktop Effects Settings and disable "appearance/blur" and "appearance/sliding popups" effects.
This helped and IDEA is usable again.


I solved a similar issue (blank windows opening the first time PyCharm was launched).

For me, this issue was an XRDP issue, fixed in CentOS 7.6 by editing /etc/xrdp/xrdp.ini and changing to max_bpp=24.
