Meta keys are stuck after unlocking client

[bagh11 0]

I have Windows 10 as synergy server and Fedora 30 as client. If I have my cursor on Fedora and press Windows + L, then it locks both my Windows and Fedora systems which I find to be a very nifty feature. However, the problem starts after this. When I unlock the systems, then it seems like the Fedora systems thinks that there is some combination of meta keys pressed (Ctrl/Alt/Windows). I can't seem to figure out which keys it thinks are pressed but pressing normal keys like e, v etc. have completely weird behavior. Also the mouse clicks stop working. 

I have not found any solution except to log out of my Fedora machine and logging back in, reconnecting Synergy to the Windows server. Any ideas on what could be going on? This is very annoying!

Thanks!
