"smart-sizing" freerdp command line option not working

[jpmv27]

What happened?

I want to use WinApps on my laptop with a HiDPI display. Even with RDP_SCALE set to 180 the windows are much too small to be usable.

Experimenting with FreeRDP directly, I found that the "/smart-sizing" option is what works best for me: the window still starts up too small but I can expand it by dragging a corner.

I tried adding "/smart-sizing" to RDP_FLAGS, but that has no effect.

Your FreeRDP version and where you got it from

# NOTES:
# - If using FreeRDP v3.9.0 or greater, you *have* to set a password
# - RDP_ASKPASS is provided as a more secure option to RDP_PASS:
#   - Calls an external command and uses its stdout as the password
#   - The password is not passed on the command line to freerdp, keeping it out of logs
#   - If specified, takes precedence over RDP_PASS

# [MOUNTING REMOVABLE PATHS FOR FILES]
# NOTES:
# - By default, `udisks` (which you most likely have installed) uses /run/media for mounting removable devices.
#   This improves compatibility with most desktop environments (DEs).
# ATTENTION: The Filesystem Hierarchy Standard (FHS) recommends /media instead. Verify your system's configuration.
# - To manually mount devices, you may optionally use /mnt.

# [ADDITIONAL FREERDP FLAGS & ARGUMENTS]
# NOTES:
# - You can try adding /network:lan to these flags in order to increase performance, however, some users have faced issues with this.
#   If this does not work or if it does not work without the flag, you can try adding /nsc and /gfx.

# [AUTOMATICALLY PAUSE WINDOWS TIMEOUT]
# NOTES:

# - This setting is ignored if 'AUTOPAUSE' is set to 'off'.
# - The value must be specified in seconds (to the nearest 10 seconds e.g., '30', '40', '50', etc.).
# - For RemoteApp RDP sessions, there is a mandatory 20-second delay, so the minimum value that can be specified here is '20'.

After further investigation, this is a limitation of FreeRDP: when combined with the /app option, the /smart-sizing option has no effect. Sorry for the noise.
