***


STEPS TO REPRODUCE
1. Download standalone version

3. Blank window, automatically closes after a few seconds if you go full screen.

OBSERVED RESULT
See step 3 in steps to reproduce.

EXPECTED RESULT
Program expected to work normally.

SOFTWARE/OS VERSIONS
Windows: 10 Pro 
macOS: n/a
Linux/KDE Plasma: n/a
(available in About System)
KDE Plasma Version: ??? (not shown)
KDE Frameworks Version: 5.88.0
Qt Version: 5.15.2

ADDITIONAL INFORMATION
CPU: Intel Core i7-2820QM @ 2.3GHz
GPU: nVidia Quadro 2000M
Memory: 8GB

As stated in the summary, program shows an entirely blank (in this case, white) window on startup. Maximizing the window crashes the program with absolutely no error message. When window is not maximized, menus can be accessed by blindly clicking near the top of the window, though changing settings around seems to achieve nothing. Performing the kdenliverc workaround fixes/changes absolutely nothing observable. GPU driver is as up to date as nVidia will allow, presently cannot afford new hardware.

Thank you for reporting. To see if this is a backend issue please try the following: settings -> Run Config Wizard -> please post a screenshot here. Settings -> OpenGL Backend -> try the 4 settings to see if Kdenlive run with one of them.
