Thanks for your reply. I compiled and tested 2.0.5-11303 and 2.0.6-11330 and the keypress leakage issue is still there. I’ve been using 2.0.4 because 2.0.5 won’t allow text to be typed into the ioquake3 player console, but that’s a separate issue. I’m configuring SDL2 with:
./configure --host=arm-raspberry-linux-gnueabihf \
I can start a new thread if that would be helpful. Disabling keyboard input to the desktop x11 server with “xinput” works around the issue but requires a wrapper script. Thanks for your help.
