Please try to disable to QuickConnect button. You can find the option in TeamViewer under "extras - options - advanced".
It just so happens that I have similar problems (Although I didn't have any of these for an entire week). Several applications are simply blank/invisible. For exemple Battle.net / LOOT / Some games..
Disabling QuickConnect Button did not solve it.
Is your monitor shutdowned / laptop closed? It's actually my case and it may causes some gpu problem because there is no physical output. I tried to start an application that was white with the --disable-gpu option and... It worked!
Still need to verify if turning on my monitor works (Not at home atm)
It indeed fixed it. Hope it'll help those who will pass by this post
To fix this problem, you need to let your monitor ON / laptop OPENED
I am facing the same problem. It only works with the laptop screen opened. If its closed the white screen problem appears.
I've never had this problem before. It begun one week ago after plug the laptop in a TV using HDMI.
I've been having similar issues with various programs when connecting to a remote computer with no monitor connected (or off, lid closed, or even without GFX installed), When stating selected program on the remote computer they would only show as a white/blank window. For me it seems only to be programs using hardware acceleration which are giving me problems, as some programs has the option to turn this off and once done, they display as they should.
Would be nice if Teamviewer could address this issue as I'm sure I'm not the only one that has remote computers running without monitors connected, turned on or labtop users with the lid closed.
Thank you for ready and how I've been helpfull to other with the issue
Please look at my explanation regarding "no monitor" in the following thread:
